Abstract
The FaddeevPopov rules for a local and Poincare-covariant procedure of Lagrangian quantization for a gauge theory with gauge group are generalized to the case of an invariance of the respective quantum actions, S(N), with respect to N -parametric Abelian SUSY transformations with odd-valued parameters p, p = 1, ..., N and anticommuting generators sp: spsq + sqsp = 0, for N = 3, 4, implying the substitution of an N -plet of ghost fields , Cp, instead of the parameter, , of the infinitesimal gauge transformations:  = Cpp. The total configuration spaces of field variables for a quantum theory of the same classical model coincide in the N = 3 and N = 4 symmetric cases. For the N = 3-parametric SUSY transformations the superspace of the irreducible representation includes, in addition to YangMills fields A, also 3 ghost odd-valued fields Cp, as well as 3 new even-valued Bpq = -Bqp and 1 odd-valued B fields for p, q = 1, 2, 3. It is shown, that in order to construct the quantum action, S(3) a gauge-fixing procedure achieved by adding to the classical action of an N = 3-exact gauge-fixing term (without introduction of non-degenerate odd supermatrix) additionally requires a 1 antighost field C, 3 even-valued Bp and 3 odd-valued Bpq fields, as well as the NakanishiLautrup field B. The action of N = 3 transformations in the space of additional fields, (3) = (C, Bp, Bpq, B), not being entangled with the fields (3) of N = 3-irreducible representation space is realized as well. These transformations are the N = 3 BRST symmetry transformations for the vacuum functional, Z3(0) = d(3)d(3) exp{(i/h)S(3)}. It is shown that the total configuration space of the fields ((3), (3)), as the space of reducible N = 3 BRST symmetry transformations, proves to be the space of an irreducible representation of the fields (4) for N = 4-parametric SUSY transformations, which contains, in addition to A the (4 + 6 + 4 + 1) ghost-antighost, Cr = (Cp, C), new even-valued, Brs = -Bsr = (Bpq, Bp4 = Bp), odd-valued Br = (B, Bpq) fields and B for r, s = 1, 2, 3, 4, r = (p, 4). The quantum action S(4) is constructed by adding to the classical action an N = 4-exact gauge-fixing term with a gauge boson, F(4) as the sr-potential as compared to a gauge fermion (3) for N = 3 case. It is proved that the N = 4-parametric SUSY transformations are by N = 4 BRST transformations for the vacuum functional, Z4(0) = d(4) exp{(i/h)S(4)}. The procedures are valid for any admissible gauge. The equivalence with N = 1 and N = 2 BRSTinvariant quantization methods are explicitly established. The finite N = 3, 4 BRST transformations are derived from the algebraic SUSY transformations. The Jacobians for a change of variables related to finite N = 3, 4 SUSY transformations with field-dependent parameters in the respective path integral are calculated. The Jacobians imply the presence of a corresponding modified Ward identity which reduces to a new form of the standard Ward identities in the case of constant parameters and describe the problem of a gauge-dependence. The gauge-independent Gribov-Zwanziger models with local N = 3, 4 BRST symmetries are proposed An introduction into diagrammatic Feynman techniques for N = 3, 4 BRST invariant quantum actions for YangMills theory is suggested. A generalization to the case of N = 2K - 1 and N = 2K, K > 2 BRST transformations is discussed1.

1 Introduction

The problem of Lorentz-covariant quantization for gauge theories with a non-Abelian gauge group [1] is a long-standing one, starting with the lecture of R. Feynman [2], showing that the naive one-loop diagram calculation within perturbative techniques with a propagator constructed, according to quantum electrodynamic, for the photon field A in the form

(1.1)

turns out to be incorrect2. A modification of calculations for reconstructing the one-loop contribution from the tree diagrams, using unitarity and analyticity [2], makes it possible to interpret the additional contributions as an input from a scalar particle, which should be, however, considered as a fermion due to the "-" sign before this summand. The solution of this problem was found by L. Faddeev and V. Popov in their celebrated work [3] by means of a trick known as the insertion of unity, providing the existence of a path integral for YangMills fields, A(x) = Am  (x)tm, given in Minkowski space-time R1,3 and taking values in a compact Lie group G, with generators tm for its Lie algebra G, in the form

respectively, for the Landau gauge, (A) = 0, (A) = A, and then with the use of the proposal of 't Hooft [5] for the Feynman gauge (A, B), (A, B) = A + g2B, with an arbitrary field B = Bmtm
known as Nakanishi-Lautrup field [6, 7]. This representation, with a gauge-invariant classical action S0 , in comparison with the case of an Abelian U (1) gauge group, essentially includes a determinant of an
non-degenerated operator M (A):

M (A) = D =   - [A, ] 4

(1.4)

known as the FaddeevPopov operator (having multiple zero-mode eigenfunctions as compared to the Abelian case, known as Gribov copies [8]). In [9] (see the review [10]), it was shown, with the use of F. Berezin [11] generalization of the Gaussian integral over Grassmann variables, that the representations (1.2), (1.3) may be equivalently presented in a local form by using fictitious scalar Grassman-odd fields C(x), C(x) = Cm(x), Cm(x) tm

with SFLP = S0 +

and similarly for Z0F , where, instead of the quantum action SFLP = SFLP (A, C, C, B), one should use the action SFFP = SFLP (A)(A,B) given in the Feynman gauge. Independently. the development of the diagrammatic technique without using Grassmann-odd fictitious fields was suggested by B. DeWitt
[4]. The representation (1.5) allows one to replace gauge transformations for YangMills fields with arbitrary scalar functions (x) = m(x)tm by global transformations in the total configuration space Mtot of fields A = (A, C, C, B), with a constant Grassmann-odd parameter , 2 = 0 by the rule
(x) = C(x), being an invariance transformation for the quantum action and for the integral measure
in (1.5), which is known as a BRST symmetry transformation [12, 13]. The BRST symmetry allows

one to prove the gauge-invariant renormalizability of a quantum YangMills theory [14], [15], as well as the path integral independence from a choice of the gauge condition for small variations. This also makes it possible to obtain the Ward identities for generating functionals of Green's functions [16]. In [17, 18] it was shown that the FaddeevPopov representation (1.2), (1.3) admits the form (1.5) for an antiBRST symmetry transformation with another Grassmann parameter, : (x) = C(x)5, which may be considered within the N = 2 BRST ( BRSTantiBRST) symmetry [19] for YangMills theories, describing ghost and antighost fields as an Sp(2)-doublet Cma(x) of fields: (Cm1, Cm2) = (Cm, Cm), as well as the parameters (, ) = (1, 2), which follows from the substitution m(x) = Cma(x)a (with summation over repeated indices). The lifting of N = 1, 2 BRST symmetry transformations, given originally in an infinitesimal algebraic form, to a finite group-like form, with finite field-dependent parameters (), a() has been introduced for N = 1 case in [23], [24] (for gauge theories with a closed algebra and general gauge theories, see [25]),for N = 2 case in [26] (as well as for constrained dynamical systems and general gauge theories in [28, 29, 30, 31] with references therein), which allows one to establish that the path integral in different gauges, such as (1.2) and (1.3), assume the same value.
Recently [27], we have examined special SUSY (distinct from space-time SUSY) transformations with m Grassmann-odd generators that form an Abelian superalgebra Gm leaving the classical action (in a certain class of field-theoretic models) invariant and realizing a lifting of Gm to an Abelian supergroup Gm, with finite parameters and respective group-like elements being functionals of field variables. We have studied some physical consequences of these transformations at the path integral level. As a consequence, we are interested in the following question.
Is it possible to find a general solution for the non-local FaddeevPopov path integral representations (1.2), (1.3) in a local form which admits an extended N = k global SUSY transformation with k  3 Grassmann-odd parameters, such as those realized by N = 1, 2 BRST symmetries? In the case of a positive solution, which depends on a possibility to realize on an appropriate N = k SUSY irreducible representation space the N = k-invariant gauge-fixing procedure to construct N = k-invariant quantum action, S(N), we are interested in investigating such physical consequences as gauge-dependence, unitarity, renormalizability and Ward identities for the Feynman diagrams in the corresponding path integral with local N = 3 and N = 4-BRST invariant quantum actions.
The paper is devoted to the solution of the problem in question and is organized as follows. In Section 2, we expound a generalization of the non-local FaddeevPopov path integral to an N = k BRST symmetry realization in Subsection 2.2, starting from the review of N = 1, 2 cases in Subsection 2.1. We derive a local FaddeevPopov path integral, Z(3), over fields composing total configuration space, which is the reducible representation superspace of N = 3 SUSY transformations being explicitly constructed both for the fields of N = 3 irreducible representation superspace and for auxiliary fields from nonminimal sector in Subsection 2.3 so as to formulate an N = 3 BRST invariant gauge-fixing procedure without a special odd supermatrix. In Section 3 we consider the fields of N = 3 irreducible and additional representation superspaces on equal footing within explicitly constructed N = 4 SUSY transformations, and formulate N = 4 SUSY invariant gauge-fixing procedure for local path integral, Z(4), in Section 4, for which these transformations are N = 4 BRST symmetry transformations. In Section 5, we determine infinitesimal and finite group-like N = k BRST symmetry transformations, for k = 3, 4, with constant and field-dependent parameters and compute respective Jacobians for changes of variables in the path integrals. In Section 6, we apply the results concerning the Jacobians so as to relate the respective path integral in different gauges, and to obtain new Ward identities, accompanied by the study of gauge dependence and gauge-invariant GribovZwanziger formulation both within N = 3 and N = 4 BRST local quantum actions for YangMills theories. The introduction into Feynman diagrammatic technique in N = 3, N = 4 BRST quantum perturbative formulations for YangMills theory is the basic point of Section 7. The results are summarized in Conclusions. The proof of an impossibility to realize N = 3 BRST invariant gauge-fixing on the configuration space consisting of only the fields of N = 3 irreducible representation superspace without an odd nondegenerate supermatrix (based on an explicit construction of quantum action and N = 3 BRST transformations) is given in Appendix A.The details of derivation

of N = 4 BRST invariant quantum gauge-fixed action in R-like gauges is considered in Appendix B.
We use the DeWitt condensed notation [32]. We denote by (F ) the value of Grassmann parity of a quantity F and also use  = diag(-, +, ..., +) for the metric tensor of a d-dimensional Minkowski space-time (generalizing the case of d = 4), with the Lorentz indices ,  = 0, 1, ..., d - 1.

The raising and lowering of Sp (2) indices, -s a, -s a = ab-s b, ab-s b , is carried out by a constant antisymmetric tensor ab, accb = ba, 12 = 1.

2 Generalization of the FaddeevPopov method

Let us consider a configuration space of fields Ai = A(x) = An(x)tn in R1`,d-1, taking their values An(x) in a Lie algebra G= su(N^ ) of a gauge group G = SU (N^ ) for n = 1, ..., N^ 2 - 1, with an action
S0(A) invariant under gauge transformations, in the condensed notations in finite and infinitesimal form Ai = Ri (A), with the generators Ri (A) of the gauge transformations:

S0(A)

=

1 2g2

ddx tr G (x)G (x), G (x) = [A](x) + A(x), A (x) ,

(2.1)

A(x)  A (x) = (x)A(x)-1(x) + (x)-1(x)  G  G = G -1,   SU (N^ ),(2.2)

(2.3)

Am  (x) = Dmn(x)n(x) = ddy Rmn(x; y)n(y) , where i = (, m, x),  = (n, y).

(2.4)

Here G (x), (x), g and Dmn(x) = mn + f monAo(x) are by the field strength, arbitrary gauge function taking theirs values in SU (N^ ), (dimensionless for d = 4) coupling constant, covariant derivative with completely antisymmetric structural constants f mno: [tm, tn] = gf mnoto of su(N^ ) and local generators of
gauge transformations, Rmn(x; y) = Dmn(x)(x - y), whereas for the infinitesimal gauge transformations (2.4) the representation, (x) = 1 + m(x)tm holds.

2.1 Review of N = 1, 2 BRST symmetry

In the case of usual BRST symmetry, the path integral, be it in Landau (1.2), Feynman (1.3), or arbitrary
admissible gauges, may be uniquely presented using a local quantum action, S = S() in the space M(toNt=1)  Mtot of fields A:

Z =

with S = S0 + ()-s = S0 +

(2.5)

for M (A) = dy A(y)(A, B) D, with the help of a gauge fermion (), encoding the gauge by a gauge function (A, B) linear in the fields A, B:

() = C(A, B) + (), () = 1, for deg. > 2, deg(A, B) = 1

(2.6)

with the use, first, the condensed notations in (2.5) and (2.6), implying the integration over some region in R1,d-1 and trace over su(N^ ) indices, second, of a nilpotent Grassmann-odd "right-hand" (left-hand) Slavnov generator -s (s), -s 2 = 0, [15] of N = 1 BRST transformations acting on the local coordinates

The quantum action S and the integration measure d are invariant under BRST transformations A  A with a constant parameter ,

A = A(1 + -s ) : A = A-s  = S = 0, sdet (/) = 1,

(2.8)

providing the invariance of the integrand in Z with respect to these transformations. In turn, for the generating functionals of Green's functions, as well as of correlated and one-particle irreducible Green's functions (known as well as, the effective action ( A )), depending, respectively, on the external sources JA, (JA) = A and mean fields, A , we have

For an N = 2 BRST symmetry realization for the quantum local action we, once again, follow the FaddeevPopov proposal (1.2), where, instead of the gauge function (A), a Grassmann-even gauge functional Y (A), (Y ) = 0, is utilized:

Now, we have all the things prepared to generalize the FaddeevPopov procedure in order to realize a more general case of N = 3 BRST symmetry for an appropriate local quantum action depending on the entire set of fields, on which the latter symmetry transformations are defined.

2.2 Proposal for non-local FaddeevPopov path integral with N = 3 BRST symmetry

There are many ways to present the functionals (1.2), (1.3) without using a determinant and a functional -function within perturbation techniques. In the case of Landau and Feynman gauges, we generalize the path integral (1.2), 1.3 by the rule

Z0L = Z0F =

dA (A) det M (A)detkM (A) det-kM (A) exp

i h

S0(A)

, k  0,

The path integral formulations with local quantum action exist for any k  N0 as follows, e.g. for (2.31):

for D[k] = (D1, ..., Dk), D  {C, C, B, B}, (C0, C0)  (C, C),

(2.33) (2.34) (2.35)

where odd-valued fields C[k], C[k] and even-valued fields B[k], B[k] taking values in Lie group G, whose numbers coincide.
However, it is not for any k that there exists a local representation for the path integral (2.33) such that the total set of fields, (k), (k) = (A, C0, C0, C[k], C[k], B[k], B[k], B) forms the representation space of Abelian group of SUSY transformations, like N = 1, 2 BRST symmetry, for k = 0, but with larger numbers of N  3, so that the Grassmann-odd: with Cl, Cl; Grassmann-even : with Bl, Bl ghost actions with Faddeev-Popov operator and gauge-fixed term with (A)B would be generated as the exact terms with respect to the action of being searched N -parametric generators of BRST symmetry transformations.
More exactly, the fact holds that
Statement 1: In order the action functional SL(k), (2.34) to be given on the configuration space of fields (k) = (A, C0, C0, C[k], C[k], B[k], B[k], B) permitting the local presentation for the path integral, ZL(0), (2.31) in the form (2.33) will be invariant with respect to N = N (k)-parametric Abelian SUSY transformations with Grassmann-odd generators -s pk : -s pk -s qk + -s qk -s pk = 0, qk, pk = 1, ..., N , and will be presented in the form:

  p1kp2k...pN k p1kp2k...pN k = N ! for k > 2,

(2.37)

with some gauge-fixing functional, F(N(k)) corresponding to the Landau gauge, so that the fields (N(k))7 should parameterize the irreducible representation superspace of the Abelian superalgebra G(N (k)) of
N (k)-parametric SUSY transformations, the spectra of integer k = k(N ) should be found as:

1) k(1) = 0, k(N ) = 2N-2 - 1, for N  2 .

(2.38)

If in addition, the gauge-fixing functional F(N(k)) should be determined without introducing auxiliary Grassmann-odd scalar or supermatrix the spectra of integer k = ku(N ) is determined by the relation:

ku(1) = 0,

Note, the local path integral ZFL(N(k)) (0) = d(N(k)) exp{(i/h)S(LN(k))((N(k)))} = Z0L for N (k) > 2 due to the presence of possible additional vertexes in fictitious fields in S(LN(k)). In addition, in the second case
7When the exponential index k in the representations (2.31), (2.32) is related to N = N (k)-parametric SUSY transformations we will denote the fields parameterizing configuration space, the quantum action and gauge-fixing functional as, (N(k)), S(LN(k)), F(N(k)) in opposite case we add "tilde" over it: (k), S(Lk), F(k) so that for N (k) = k in general: (N(k)) = (k), S(LN(k)) = S(Lk).

the requirement of the irreducibility of the G(N (k)) (finite-dimensional) representations for each N (k) is weakened. The irreducibility will be hold only for even N : N = 2K, K  N.

Indeed, this leads, for N = 1, k(1) = 0, to the standard FaddeevPopov representation (1.5) with the BRST symmetry, whereas, for k(2) = 0, this leads to the N = 2 BRST symmetry with a local path integral (2.16).

For N = 3, k(3) = 1, there arises a first non-trivial case for the case 1 (2.38) and ku(3) = 3 for the case 2 (2.39) of the Statement. For N = 4 for both cases we have from (2.38), (2.39): k(4) = ku(4) = 3.

The validity of the first part (2.38) follows from the simple fact that any field finite-dimensional

part in fields Cp, Bp1...pl, B, for l = 2, ..., N - 1, due to the last equation in (2.43) has the length,

The Grassmann-odd and Grassmann-even numbers of new degrees of freedom for additional to A fields in the multiplet k(N) of the irreducible representation of the superalgebra G(N ) without decomposition in su(N^ ) generators tm are equal to, (2N-1, 2N-1 - 1). Indeed, for N = 1, the only ghost

field C(x) contains in N = 1 irreducible multiplet. For N = 2, two ghost-antighost Cp  Ca, a = 1, 2

and Nakanishi-Lautrup, B2  B, fields. Then, first, extracting the degrees of freedom relating to the usual ghost and antighost C, C and B fields, second, dividing any subset on pairs of Grassmann-odd

(and Grassmann-even) fields as it is given in (2.34), we get to the value of k = k(N ) for the respective

exponent of the determinants in (2.31):

2N-2 - 1, 2N-2 - 1 . (2.44)

However, we meet the problem when going to construct the action functional (quantum action), S(LN(k)), by the rule (2.36) for odd N = 2K - 1, in particular, for N = 3 SUSY transformations on the G(N )irreducible representation superspace. Indeed, the respective gauge-fixing functional, F(3) (3) due to the linear part of the N = 3 SUSY transformations (2.41), (2.43) should be, at least, quadratic in the fields A. The fact that, the Grassmann parity of F(3)) determines it as the fermion, (F(3)) = 1, means the necessity to introduce some additional Grassmann odd non-degenerate supermatrix in order to realize the prescription (2.36) for the quantum action. The details of using of such kind of odd supermatrix, which should both to determine the required Grassmann parity of F(3) and to change the basis of additional fields (C, B) in the configuration space parameterized by (3 to construct N = 3 SUSY invariant action S(L3)((3)) for k(3) = 1 are considered in the Appendix A.
For k(N ) N=5;6,... = 7; 15, . . ., etc, the situation is more involved, and we leave its detailed consideration out of the paper scope (see as well comments in the Conclusions).

The validity of the second part (2.39) of the Statement we consider here only for N = 3 case, whereas
for even, N = 2K, case its both parts (2.38) and (2.39) coincide.
To do so we should determine the total configuration space, M(toNt=3)  M(to3t), the fields parameterizing it, (3), (3) =(3) being sufficient to construct the (bare) quantum action, S(L3), must form a finitedimensional field completely reducible representation of Abelian G(3) superalgebra. That means, that on the fields (3) it will be realized the another irreducible representation of N = 3-parametric G(3) superalgebra not being entangled with the irreducible G(3)-representation acting on the fields (3).
First of all, let us find exactly the action of the generators -s p of G(N )-representation for N = 3 on
the fields (3), (3) = A, Cp1 , Bp1p2 , B(3) = B parameterizing irreducible representation superspace from (2.41) (2.43). Lemma 1: The action of the generators -s p of the Abelian superalgebra G(3) on the fields (3) is given by the relations:

A-s p = A-s p0 = D(A)Cp and Cp1 -s p0  0.

(2.46)

Since, first,

A -s p0-s r0 + -s r0-s p0 = 0,

(2.47)

we must add to -s p0 the nontrivial action of new -s p1 on Cp1 (vanishing when acting on A: A-s p1  0), starting from the Grassmann-even triplet of the fields Bp1p2 = Bprmtm (BRST-like variation of Cp1 )

providing the validity of the last row in the table (2.45). In deriving (2.60) the use has been made of the symmetry for the commutator [Cp, Cr] = [Cr, Cp], and the following relations

Bp[p1 , Cp2] , Cp3 + Bp1p2 , Cp , Cp3 = pp1p2 P p3 ,

B[pp3 , Cp1 , Cp2] - B[pp3 , Cp2] , Cp1 + C[p, Bp1p3 , Cp2] = pp1p2 Qp3 ,

Bpp3 , Cp1 , Cp2 pp1p2 ,

(2.61) (2.62) (2.63)

11

as well as the Jacobi identities, which establish the absence of the 4-th power in the fields Cp in the transformation for B (2.58):

(2.64)

meaning that we may put (B4) = 0. One can easily see that the 3  3 equations (2.57) considered for B

are fulfilled as well:

B -s p[31]-s p[32] + -s p[32]-s p[31] = 0  -s {[3p]1 -s p[32]} = 0.

(2.65)

Therefore, -s p = -s p[3] are the generators of the irreducible representation of G(3) superalgebra of N = 3-

parametric transformations in the field superspace, M(m3i)n, parameterized by the fields, A(33). That fact

completes the proof of the Lemma 1.

Thus, in order to have the superspace of irreducible representation being closed with respect to the action of abelian Lie superalgebra G(3) with Grassmann odd scalar generators -s p this superspace should parameterized by the set of fields:

{A(33)} = A, Cp, Bp1p2 , B = An, Cpn, Bp1p2n, Bn tn

(2.66)

used as local coordinates in the configuration space M(m3i)n with dimension: dim M(m3)in = (N^ 2 - 1) d + 3, 3 + 1 , for an irreducible gauge theory of the fields A with a non-Abelian gauge group SU (N^ ). It is obvious that M(m3)in  M(toi)t for i = 1, 2. We will call M(m3i)n as the minimal configuration space.
Now, due to insufficiency of the M(m3i)n to provide gauge-fixing procedure without using of additional odd supermatrix or Grassmann-odd parameter let us extend the M(m3i)n by the fields (3) of so-called non-minimal sector, starting from a new antighost field, C(x) = Cm(x)tm, to provide a determination of the gauge fermion F(3)  (3) as the quadratic functional for the Landau gauge, (A) = 0:

L(3)(C, A) = ddx tr C(A).

(2.67)

Properly the fields (3) contain the Nakanishi-Lautrup fields, B, and have the contents

(3) = C, Bp, Bp1p2 , B ,  C, Bp1p2 + (1, 1) =  Bp1 , B = (0, 0)

(2.68)

with even and odd degrees of freedom, (3+1, 1+3) (modulo dim SU (N^ ) indices) and determine the action of generators -s p(n) of the representation of the Abelian superalgebra G(3) in the superspace, M(n3m) , with
the local coordinates (3). Lemma 2: The action of the generators -s p(n) of the Abelian superalgebra G(3) on the fields (3) is determined by the relations:

C-s p(n) = Bp, Bp1 -s p(n) = Bp1p, Bp1p2 -s p(n) = p1p2pB, B-s p(n) = 0.

The (3)

respective N are given by

Indeed, the relations (2.69) repeat by its form linearized chain (2.41) (2.43) without non-linear terms. It easy to check, that the generators -s p(n) satisfy to the defining relations:

-s p(n1)-s p(n2) + -s p(n2)-s p(n1) = 0,

4
-s p(nl ) = 0.
l=1

(2.70)

12

In particular, we have the exact sequence

C, Bp, Bp1p2 , B  -s p(n3) Bp3 , Bpp3 , p1p2p3 B, 0  -s p(n4) Bp3p4 , pp3p4 B, 0, 0  -s p(n5) p3p4p5 B, 0, 0, 0  0 -s p(n6) (2.71)
of the length, equal to 4.

We will call the representation (2.69) as the N = 3 trivial representation of the superalgebra G(3).

Finally. we construct the reducible representation of the superalgebra G(3) in the total configuration

space, M(to3t), parameterized by the fields, (3), (3) = (3) , with dimension in each space-time point x  R1,d-1,

dim M(to3t) = (N^ 2 - 1) d + 23 - 1, 23 .

(2.72)

The generators of this representation we will denote as, -s pto3t = -s p3 + -s p(n3), (and then we will omit index "tot" in it as it done for the generally-adopted notations in N = 1, 2 BRST symmetry cases). The action of -s pto3t is completely determined by (2.45) and (2.45).
Now, let us turn to the gauge-fixing procedure, construction of the quantum action and path integral, whose integrand will be invariant with respect to derived N = 3 SUSY transformations.

2.3 N = 3 BRST-invariant path integral and quantum action

Let us determine the local path integral, Z3, and generating functionals of Green functions in any ad-
missible gauge, turning to the non-degenerate Faddeev-Popov matrix, for Yang-Mills theory underlying above constructed explicit N = 3 SUSY invariance (2.45), (2.69) in the total configuration space M(to3t), with triplet of anticommuting parameters p and the local quantum action S(3) ((3), (3)) given by the prescription (2.36) as follows:

with gauge fermion functional, (3) = (3) (3) , depending on the fields (3) as follows (confer with (2.6)):

(2.75)

and external sources JAt3 = JA3 , J An3 to the respective Green functions related to the fields A(33), A(3n3) with the same Grassmann parities: (JA3 ) = (A(33)), (J An3 ) = (A(3n3) ).

It is easy to check that both the' functional measure, d(3)d(3) = d(3), as well as the quantum action, S(3) , are invariant with respect to the change of variables, A(3t)  (A3)t generated by N = 3 SUSY transformations (2.45), (2.69), with accuracy up to the first order in constant p (equally with
infinitesimal p):

(A3)t = A(3t)(1 + -s pp) : A(3t) = A(3t)-s pp = S(3) = o(), sdet (3)/(3) = 1 + o(), (2.76)

We will call, therefore, the transformations:

A(3t) = (A3)t - A(3t) = A(3t)-s pp,

(2.77)

with the explicit action of the generators -s p (2.45), (2.69) on the component fields as N = 3-parametric BRST transformations.

13

The particular representations for the path integrals (2.73), (2.74) in the Landau and Feynman gauges are easily obtained within the same R-family of the gauges as for the N = 1 BRST invariant case (2.5) due to obvious coinciding choice of the gauge functions, (3)(A, B), for (3) = 0, in (2.75) with one, (A, B) = (A + g2B = 0), in (2.6). The quantum action, S(3) , has the representation:

(2.82) (2.83) , (2.84) (2.85)
(2.86)

where the latter relations (2.84)(2.86) appear by readily established Leibnitz-like properties of the generators of N = 3 BRST transformations, -s p acting on the product of any functions A, B with definite Grassmann parities depending on the fields A(3t). Indeed, e.g. the validity of (2.84) follows from the calculation of variations:

A = AA (3t) A(3t)-s p p = AA (3t) A(3t)-s p  A-s p, (AB) = (A)B + A(B) = (A-s pp)B + A(B-s pp) = (A-s p)B(-1)(B) + A(B-s p)

(2.87) p,(2.88)

and the same for the second: 1 2(AB), and third: 12 2 (AB) variations.
For instance, the ghost-dependent functional, Sadd(3), with cubic and quartic in fictitious fields terms is derived from the expression:

Sadd(3)

=

1 6

ddx tr 3Bp M (A)Cq, Cr + D(A)Cq, Cr

(2.89)

+ C 2 M (A)Cp, Bqr + 2 D(A)Cp, Bqr - M (A)Bpr, Cq - D(A)Bpr, Cq

+ M (A)Cr, Cp , Cq + D(A)Cr, Cp , Cq + D(A)Cr, Cp , Cq pqr,

where we have omitted vanishing terms, Cp, Cq pqr  0, and with use of the antisymmetry in p, q, r as well as the integration by parts the representation (2.81) immediately follows from (2.89). Note, the each term in Sadd(3), which determine the interaction vertexes from the sector of fictitious fields, contains the

14

space-time differential operator for any gauge from R-gauges, that looks as more nontrivial analog of Sadd (2.20) for N = 2 BRST symmetry.

Let us study some consequences of the suggested N = 3 BRST transformations. As in the N = 1, 2

BRST case, the N = 3 invariance, for the corresponding generating functionals of Green's functions,

Z3|(J ) , W3|(J ) and effective action, 3|( (3) ): 3|( (3) ) = W3|(J ) - JAt A(3t) , JAt = -(3|/ A(3t) ), A(3t) = - A(Jt)W3|(J ),

(2.90)

with a given gauge condition (3)((3)), leads to the presence of an G(3)-triplet of Ward identities:

JAt A(3t)-s p (3),J = 0,

JAt

A(3t)-s p

(3),J = 0,

3|  A(3t)

A(3t)-s p (3)  = 0,

(2.91)

with respective normalized average expectation values M , (3),J M , (3),J M , (3),  so that

1 (3),J = 1, for a functional M = M ((3)) calculated using Z3|(J ), W3|(J ), 3| for a given gauge fermion (3) in the presence of external sources , JAt and mean fields A(3t) . The gauge independence

of the path integral Z3|(0)  Z3|(3) (0) under an infinitesimal variation of the gauge condition, (3)  (3) + (3):

Z3|(3)+(3) (0) = Z3|(3) (0).

(2.92)

is established using the infinitesimal FD N = 3 BRST transformations with the functional parameters,

p() =

1 3!

i/h

(3)()-s q-s rpqr, .

(2.93)

which we consider in details in the Section 5.

The equivalence of N = 3 and N = 1 BRST invariant path integrals Z3|(0) (2.73), Z (2.5),. e.g in R-like gauges immediately follows from the structure of the quantum action S(3) , (2.78). Indeed,
integrating by the fields Bpq, second, with respect to Cp, then trivially with respect to Bp and Bpq we get:

is the N = 1

BRST invariant quantum action (2.5) given in the R- gauges. The functional Z coincides with one

given in (2.5) after identification for the field B as B = C which plays now the role of the ghost field.

The crucial point of the found N = 3 BRST symmetry transformations in M(to3t) that the whole fields (3) due to the relations (2.38), (2.39) of the Statement leading to: ku(3) = k(4) = ku(4), maybe organized in the respective multiplet of N = 4 field irreducible SUSY transformations with constant 4 Grassmann-
odd parameters, r, r = 1, 2, 3, 4. The construction of the respective N = 4 SUSY transformations will be the main aim of the next Section.

3 N = 4 global SUSY transformations

Before introducing the N = 4 SUSY transformations we consider additional N = 1-parametric SUSY

transformations in M(to3t) with new anticommuting with triplet of p:

Grassmann-odd p + p = 0,

nilpotent where as

generator, for N = 1

[18] the role of the antighost field C, as well as the rest multiplet (2.68) (3) from the non-minimal sector

should be considered in opposite way ac compared to the multiplet (3) = A, Cp1, Bp1p2 , B from the G(3) irreducible (minimal) representation.

3.1 Additional N = 1 BRST transformations on the fields of N = 3 representation

It is valid the following Lemma 3: The action of the generator -s of the Abelian superalgebra G(1) on the fields

parameterizing M(to3t) is determined by the relations:

, on that

the only

fields (3) the field C

appears by the active (as compared to Cp) connection.

To prove the correctness of (3.1) it is sufficient to check, the nilpotency of -s on each field from the

multiplet, the gauge

Ri (A)- j Rj (A) - (-1) Ri (A)- j Rj (A) = -FRi (A), for F = f mnl(x - z)(x - y). (3.2)
The nilpotency on any other fields follows, first, from the Leibnitz rule of acting of -s on the commutator of any functions A, B with definite Grassmann parities:

A, B -s = A-s , B (-1)(B) + A, B-s ,

(3.3)

second, from the Jacobi identity: A, C , C (-1)(A) - C, A , C + C, C , A (-1)(A) = 0,

(3.4)

for any A  C, Bp1 , Bp1p2 , Cp1 , Bp1p2 , B, B . E.g. for Grassmann-even A = Bp1p2 we have,

(3.5)

where we have used the relations (3.1), linearity and Leibnitz rule (3.3) for -s , Jacobi identity (3.4) and

generalized antisymmetry for the (super)commutator.

The transformations,

(3)  (3) = (3)(1 + -s ) = (3) +  (3),

appear by the invariance transformations of following path integral and quantum action:

(3.6)

Z1|(0) =

d(3)d(3) exp

i h

S(1)

(3), (3)

, with S(1) = S0(A) + (1)-s ,

(3.7)

16

with a new gauge fermion functional, (1) = (1) (3) , which should determine a non-degenerate

quantum action S(1) on the Mt(o3t), i.e. with non-degenerate supermatrix of the second derivatives in

A(3t), B(3t)

of

S(1)

evaluated -

on

of

the

solutions,

(A0 , 0, ..., 0)

of

the

respective

equations of motions: S0  j = 0:

(1) = B(1)(A, B) + CpBqrpqr + (1)((3)), for deg.(1) > 2, deg(1)(A, B) = 1.

(3.8)

Indeed, from the invariance of the integration measure, d(3), and quantum action, S(1) , due to the same reason as for the standard N = 1 BRST realization in Mtot (2.8):

 S(1) = 0, d(3) = d(3)sdet (3)/(3) = d(3),

(3.9)

it follows the invariance of the integrand in Z1|(0) with respect to these transformations. It justifies a definition of the transformations (3.6) as N = 1 antiBRST symmetry transformations in M(to3t).
Choosing, (1)((3)) = 0 in (3.8) for the quadratic gauge functional, (1), (in particular, for Rgauges: (1)(A, B) = (A, B)) we find for the quantum action, S(1) , the representation:

S(1) = S0(A) + ddx tr A + g2B B + BM (A)C + BpBqr + CpBqr pqr + Sadd(1),(3.10)

Sadd(1) = ddx tr Cp Bqr , C + Cp, C Bqr pqr.

(3.11)

Integrating out of Bp, Bqr fields we get for the path integral:

Z1|(0) =

dAdBdCdBdCpdBqr(Bq1r1 )(Cp1 ) exp

i h

S (1)

+ Sadd(1)

(3.12)

=

dAdB dC dB exp

i h

S

(1)

with S = S0(A) +  (1) -s ,  (1) = B(1)(A, B),(3.13)

where the resulting (after integration) fields A(1), in fact, coincide with the fields given by the local formulation for the path integral (2.5) within Faddeev-Popov rules with N = 1 BRST symmetry, in
particular, for the Landau gauge (1.5) under identification:

A(1) = A, B, C, B  A = A, C, C, B .

(3.14)

The only difference consists in the realization N = 1 antiBRST symmetry for Z1|(0) given in M(to3t) and of N = 1 BRST symmetry for Z (2.5) determine over Mtot. After replacing (B, C)  (C, C) the above path integral will coincide exactly
Thus, we reached the validity of the
Statement 2: The path integral, Z1|(0), (3.7) with the quantum action, S(1) , (3.10) at least, for the
special quadratic gauge fermion, (1), (3.8) with (1) = 0 determined in N = 3 reducible representation space, M(to3t), of G(3) superalgebra, but with realization of the additional N = 1 antiBRST symmetry (3.1), (3.9) coincide with respective path integral (3.12), with the quantum action, S, (3.13) obtained with use of N = 1 antiBRST symmetry transformations acting in the standard configuration space, Mtot.
Now, we may reveal the physical contents of the fields spectrum for the Z3|(0) (2.73), S(3) (3) (2.78)(2.81) being invariant with respect to N = 3 BRST symmetry transformations (2.45), (2.69). Namely, the fields B, C from M(to3t) space correspond respectively to the pair of ghost field C inheriting the gauge symmetry and antighost field, C, introducing the gauge condition in the gauge fermion for N = 1 BRST symmetry realization of the standard Faddeev-Popov path integral. The triplet of the ghost fields

forms the

pairs of N = 3 triplet of Grassmann-even ghost-antighost pairs: Bp, Bp . The role of the Nakanishi-

Lautrup field B remains the same as in case of standard N = 1 BRST symmetry formulation, i.e. as the

Lagrangian multiplier (at least for Landau gauge) introducing the gauge into the quantum action.

Because of, the term in the ghost part, Sgh(3), (2.80) with Grassmann-even triplet of ghost-antighost pairs maybe presented as follows,

1 2

ddx tr BpM (A)Bqrpqr 

ddx tr BpM (A)Bp

(3.15)

we can immediately identify the fields, (C0, C0; C[3], C[3]; B[3], B[3]) in the quantum action (2.34) for the local representation (2.33) of the generalized path integral (2.31) , for ku(3) = 3, with singlet and Grassmann-odd and Grassmann-even triplets of ghost pairs as follows:

C0, C0; C[3], C[3]; B[3], B[3] = B, C; Cp, Bp; Bp, Bp, .

(3.16)

Note, first, that for N = 1 antiBRST symmetry realization in the configuration space M(to3t) it is possible in addition to the path integral formulation (3.7) introduce all necessary for diagrammatic Feynman tech-

nique generating functionals of Green functions as it was done for N = 1 and N = 3 BRST symmetry case

in the Subsections 2.1, 2.3 and study theirs respective properties (Ward identities, gauge-independence

problem). Second, as for the above developed N = 1 antiBRST symmetry concept in M(to3t) it is possible

and finishing with the construction of the respective path integral, whose action and functional measure should be invariant with respect to these transformations. We leave the details of this interesting concept out of the paper scope.

3.2 N = 4 = 3 + 1 SUSY transformations

Now, we are able to consider the triplet of the Grassmann-odd ghost fields Cp and singlet C, triplets of the Grassmann-even ghost fields Bpq and Bp, triplet of new Grassmann-odd ghost fields Bpq and singlet B on the equal footing within corresponding Grassmann-odd quartet, Cr, Grassmann-even sextet, Br1r2, and Grassmann-odd quartet, Br1r2r3 for r, r1, r2, r3 = 1, 2, 3, 4 as the elements (with the fields A, B) of the irreducible tensor representation of the Abelian G(4) superalgebra. In fact, the N = 3 and N = 1
representations of G(3) and G(1) superalgebra in the same G(3)-representation space of the fields (3) are nontrivially entangled in unique N = 4 irreducible representation in the same representation space M(to3t) = M(to4t) whose local coordinates (fields) are organized into G(4)-irreducible antisymmetric tensors, as well as the parameters and generators have the structures:

(r1, r2, on the

SUSY transformations with as: (4) = (4)-s rr.

The form of the transformations (3.20) follows from the chain (2.41), (2.43) for N = 4. To prove the Lemma we will follow the algorithm elaborated when the Lemma 1 was proved. We start from the boundary condition for the transformations (3.20) inherited from the gauge transformations for A (2.40)
and present the realization for the sought-for generators as series:

-s r = -s re :

A-s r = A-s r0 = D(A)Cr and Cr1 -s r0  0.

In deriving (3.35)(3.37), the use has been made of the symmetry for the commutator [Cp, Cr] = [Cr, Cp], Jacobi identities both for (Bpp1 , Cp2], Cp3 ) and for (Cp1 , Cp2], Cp3 ), which establish the absence of the 4-th power in the fields Cp in the transformation for Br1r2r3 (3.33) completely repeating the equations (2.64) for N = 3 case, but with replacement: Bp1p2 , B, Cp, -s p[3] on Br1r2 , Br1r2r3 , Cr, -s r[3] .

(3.41)

providing the validity of the last row in the table (3.20). In deriving (3.41), we have used the above
mentioned properties found when establishing (3.35)(3.37) as well as the Jacobi identity for the fields Br1r2r3, Cr4 , Cr5 ) with the following representations for "4-cocycles", i.e. for 5-th rank tensors being antisymmetric in 4 indices:

transformations for B (2.45). One can immediately check that the equations (3.40) considered for B,

instead of Br1r2r3 , are fulfilled as well:

B -s r[41]-s r[42] + -s r[42]-s r[41] = 0  -s {[4r]1 -s [r42]} = 0.

(3.44)

Therefore, -s r = -s r[4] are the generators of the irreducible representation of G(4) superalgebra of N = 4-
parametric SUSY transformations in the field superspace, Mt(o4t), parameterized by the fields, A(44). That fact completes the proof of the Lemma 4.

Note, first, that the transformations on the fields Br1r2 , Br1r2r3 , B do not contain the terms more than
cubic in the fictitious fields, whereas they depend linearly on the fields B's in the cubic terms. Second, the quantities, Qr4 do not enter into the transformations for Grassmann-even field B as compared to its N = 3 analogs, Qp, which are essentially presented in the transformations for Grassmann-odd B.

Now, we have all necessary to construct N = 4 G(4)-invariant quantum action for the YangMills theory.

4 N=4 BRST invariant gauge-fixing procedure and local path integral
Let us determine according to the prescription (2.33), (2.36) the local path integral, Z4, generating functionals of Green functions in any admissible gauge, turning to the non-degenerate Faddeev-Popov matrix, for Yang-Mills theory underlying above constructed explicit N = 4 SUSY invariance (3.20) in
21

the total configuration space M(to4t), M(to4t) = M(to3t), with quartet of anticommuting parameters r and the local quantum action SY(4) ((4)) as follows:

W4|Y

.

(4.2)

with use of the compact notation for, r1r2r3r4  [r]4. Here, W4|Y (J(4)) is the generating functionals of connected correlated Green functions and gauge boson functional, F(N(4)) = Y(4) = Y(4) (4) , depends on the fields (4) as follows (confer with Y (2.17) for N = 2 BRST symmetry):

Y(4)((4)) = Y(04)((4)) + Y(4)((4)), for degY(4) > 2, degY(04)((4)) = 2,

(4.3)

and JAt4 are the external sources (coinciding with ones for N = 3 case, JAt3 ) to the Green functions related to A(4t4) with the same Grassmann parities: (JAt4 ) = (A(4t4)).
It is not difficult to check that both the' functional measure, d(4), as well as the quantum action, SY(4) , are invariant with respect to the change of variables, A(4t)  (A4)t generated by N = 4 SUSY transformations (3.20) with accuracy up to the first order in constant p (equally with infinitesimal p):
(A4)t = A(4t)(1 + -s rr) : A(4t) = A(4t)-s rr = SY(4) = o(), sdet (4)/(4) = 1 + o(), (4.4)

These properties justify the definition of the transformations:

A(4t) = (A4)t - A(4t) = A(4t)-s rr,

(4.5)

with the explicit action of the generators -s r (3.20) on the component fields as N = 4-parametric BRST transformations for the functionals Z4|Y (0), Z4|Y (J(4)).
The particular representations for the path integrals (4.1), (4.2) in the Landau and Feynman gauges may be obtained within the same R-family of the gauges as for the N = 1, 2, 3 BRST invariant cases (2.5), (2.17), (2.73). To do so we determine the quadratic gauge boson functional, Y(04)((4)), which should generate R-like gauges as follows:

Y(04)((4)) = Y(04)(A) + Y(B4)(Brs) =

with some Grassmann-even functional S vanishing in the Landau gauge ( = 0). To derive (4.7)(4.10) we have used the relations (2.82)(2.86), (3.3) being adapted for N = 4 BRST symmetry, as well as the following from (2.86) Leibnitz-like property of the generators, -s r acting on the product of any functions A, B with definite Grassmann grading:

(AB) -s r1 -s r2 -s r3 -s r4 [r]4 = A-s r1 -s r2 -s r3 -s r4 B + 4A-s r1 (B-s r2 -s r3 -s r4 ) (-1)(B)

The detailed derivation for the quantum action, structure of the additional -dependent term, S, are considered in the Appendix B. Note, the each terms in Sadd(4) contain space-time derivative and, in particular, the second-order differential operator (Faddeev-Popov operator) for any gauge from R-gauges, as for the Sadd(3) (2.89) for N = 3 BRST symmetry. For the Landau gauge, the summands in Sadd(4) proportional to the Lorentz condition: (A) = 0, may be omitted therein due to the presence of ((A)) in the functional integral (4.1) after integrating over the fields B.
The equivalence of N = 4 and N = 1 BRST invariant path integrals Z4|Y (0) (4.1), Z (2.5),. e.g in the Landau gauge determined by the gauge functional Y(04)(A) (4.6) follows analogously to the derivation (2.94) for N = 3 case from the structure of the quantum action SY(4) , (4.7)(4.10). Indeed, using the representation for SY(4) (B.22) in terms of dual G(4)-tensor fields Br1r2 , Cr (B.20), (B.21) let us divide the quartets of ghost Grassman-odd fields Cr, Cr as G(3)-triplets and singlets which permits to present the respective term in the ghost part of the action as:

Cr; Cr = (C, Cp); (C, Cp)  CrM (A)Cr = CM (A)C + CpM (A)Cp,

(4.12)

for r = (1, p), p = 1, 2, 3 and C  -B234. Because of the remark above we may omit the terms with
(A) with except for Nakanishi-Lautrup field B and therefore integrate by the fields Cp, second, with respect to Cp, and then trivially with respect to Br1r2 and Br1r2 for 1  r1 < r2  3 as follows:

(4.13)

The functional Z exactly coincides with one given in (2.5) in the Landau gauge.
Again, the N = 4 BRST invariance, for the corresponding generating functionals of Green's functions, Z4|Y (J(4)) , W4|Y (J(4)) and effective action, 4|Y ( (4) ) determined by the same rule as for its N = 3 analog (2.90) with a given gauge condition Y(4)((4)), leads to the presence of an G(4)-quartet of Ward identities:

JAt4 A(4t4)-s r Y(4),J = 0,

with corresponding normalized average expectation values (as in (2.91)) in the presence of the external sources JAt4 and mean fields A(4t4) . The gauge independence of the path integral Z4|Y (0)  Z4|Y(4) (0) under an infinitesimal variation of the gauge condition, Y(4)  Y(4) + Y(4):

Z4|Y(4)+Y(4) (0) = Z4|Y(4) (0)

5 N = k, k = 3, 4 infinitesimal and finite BRST transformations and their Jacobians
Here, we consider the algorithm of construction of finite N = k BRST transformations starting from its algebraic (infinitesimal) proposals respectively for k = 3, 4 cases and calculate theirs Jacobians together with some physical corollaries.

5.1 N = 3 BRST transformations
The finite N = 3 BRST transformations acting on the fields A(3t3), parameterizing configuration space M(to3t), are restored from the algebraic (equivalently, infinitesimal for small p) N = 3 BRST transformations, generalizing the recipe [26] for N = 2 BRST symmetry and following to [27], [35] in two equivalent ways. First, the derivation is based on the condition which follows for any -s p-closed regular functional K (3) to be invariant with respect to right-hand supergroup transformations and, second, from the Lie equations :

1) K g(p)(3) = K (3) and K-s p = 0  g (p) = exp {-s pp} ,

recipe proposed in [26] for an irreducible gauge theory with a closed algebra (including the YangMills

where trG(4) denotes trace over matrix G(4)-indices. The justification of the representation (5.23) is based on the same points (5.6)(5.10) as for its N = 3 analog (5.5), whose detailed calculation we leave out of

6 Correspondence between the gauges, Ward identities, gauge dependence, gauge-invariant GribovZwanziger model.

Here we consider the physical properties of the respective N = 3, N = 4 finite BRST transformations, including extended by sources (antifields) to the N = 3 or N = 4 BRST transformations effective actions in the Subsection 6.1 and its applications in the Subsection 6.2 to the GribovZwanziger model [36] with gauge-invariant horizon functional suggested in [37] with preservation of the local N = 1, 2 BRST invariance, shown in [38], [39].

6.1 FD Finite N = 3, 4 BRST Symmetry for Ward identities and Gauge Dependence Problem.

First, let us study a relation that exists among the path integrals underlying N = 3 BRST symmetry, Z3|(3)0 (0) and Z3|(3)0+(3) (0) in different admissible gauges, one of which being described by a Grassmann-odd gauge functional (3)0 corresponding to the Landau gauge (2.75) for  = 0. The other one ((3)0 + (3)) corresponds to any family from the gauges within the (3)((3)), including R-gauges for (3) = 0 in (2.75) and for (A, B) = (A + g2B = 0) within the functional (3)((3)). To this end, we use a finite FD N = 3 BRST transformation with functionally-dependent parameters ^p1 |(3)
(5.11), the N = 3 BRST invariance of the quantum action, S(3) (3) (2.78) for  = 0, and the form of the Jacobian, J(3) (3) , (5.12) of a corresponding change of variables, (3)  (3)g~(^), given as follows

The coincidence of the vacuum functionals Z3|(3)0 (0) and Z3|(3)0+(3) (0), evaluated with the respective fermionic functionals (3)0 and (3)0 + (3), takes place in case there holds a compensation equation for an unknown Fermionic functional  = ((3)):

with opposite sign than in (2.93) because of we started here from the gauge determined by (3)0 instead of (3)0 + (3) in (2.92). Therefore, for any change (3) of the gauge condition (3)0  (3)0 + (3), we can construct a unique FD N = 3 BRST transformation with functionally-dependent parameters (6.4) that allows one to preserve the form of the path integral (6.1) for the same YangMills theory. On the another hand, if we consider the inverse form of compensation equation (6.2) for an unknown gauge variation (3) with a given  (3) , we can present it in the form

obtain

the

integral

Z , (3)0+(3)

evaluated,

however, in a gauge determined by the Fermionic functional (3)0 + (3), in complete agreement with

(6.7).

This latter, in particular, implies that we are able to reach any gauge condition for the partition function within the R-like family of gauges, starting, e.g., from the Landau gauge and choosing: (3) = g2 ddxtr CB (for  = 1 in the Feynman gauge).
Making in Z(3) (J(3)) an FD N = 3 BRST transformation, (3)  (3)g~(^) and using the relations (5.12) and (6.3), we obtain a modified Ward (SlavnovTaylor ) identity:

J(3)

d(3) L exp

i h

S(3) + JC3t (C33t)

, with 1 (3),J(3) = 1 .

(6.9)

Due to the presence of  (3) , which implies functionally dependent ^p(), the modified Ward identity
depends on a choice of the gauge Fermion (3) (3) for non-vanishing J(3), according to (6.3), (6.4), and therefore the corresponding Ward identities for Green's functions, obtained by differentiating (6.8) with respect to the sources, contain the functionals ^p() and their derivatives as weight functionals. Due to
(6.8) for constant p, the usual G(3)-triplet of the Ward identities (2.91) for Z3|(3) (J(3)) follow from the first order in p.
Then, taking account of (6.4), we find that (6.8) implies a relation which describes the gauge dependence of Z3|(3) (J(3)) for a finite change of the gauge, (3)  (3) + (3):

Z J 3|(3)+(3) (3) = Z3|(3) J(3)

exp

i h

29

so that on the mass-shell for Z3|(3) J(3) : J(3) = 0, the path integral (and therefore the conventional physical S-matrix) does not depend on the choice of (3) (3) .
Let us introduce extended generating functionals of Green's functions by means of sources KC3t|p, KC3t|pq = -KC3t|qp, KC3t , ((KC3t|p) = (KC3t|pq) + 1 = (KC3t ) = (C3t ) + 1), introduced respectively to N = 3 BRST variations (C33t)-s p, (C33t)-s p-s q, and (C33t)(-s )3:

Making in (6.11) a change of variables, which corresponds only to N = 3 BRST transformations (C33t)  (C33t)g~(^) with an arbitrary functional ^p((3)) from (6.4), we obtain a modified Ward identity for

The Ward identities (6.19) are interesting as they remind of the behavior of the extended quantum

action S(3) (3), Kp, Kpq, K (6.14)  being the tree approximation for the extended effective action (3) within the loop expansion  and serve as generating equations for a corresponding G(3)-covariant
method of Lagrangian quantization, covering the case more general than a gauge group.

In turn, the case of N = 4 finite BRST transformations permits to get the same results with some
peculiarities. We restrict ourselves by only derivation of the respective modified Ward identity and description of the gauge dependence problem, being based on the solution of the compensation equation
from the change of variables in Z4|Y (0) (4.1) generated by FD N = 4 BRST transformations with quartet of the parameters ^r((4)) (5.24) with jacobian J(4)((4)) (5.25)

The solution of (6.21) for an unknown  (4) and hence of ^r (4) , with accuracy up to N = 4 BRST exact terms, is given in terms of the function g(z) (6.3)

Thus, for any change of variables in the path integral Z4|Y(4) given by finite FD N = 4 BRST transformations with the parameters ^r (5.24), we obtain the same path integral Z , 4|Y(4)+Y(4) evaluated, however, in a gauge determined by the Bosonic functional Y(4) + Y(4).
Making in Z4|Y(4) (J(4)) an FD N = 4 BRST transformation, (4)  (4)g~(^) and using the relations (5.25), (6.22) and (6.23), we obtain a N = 4 modified Ward (SlavnovTaylor ) identity:

(6.26)

where the source-dependent average expectation value corresponding to a gauge-fixing Y(4) (4) is determined as in (6.9) for N = 3 case. Due to  (4) , which implies functionally dependent ^r(), the modified Ward identity depends on a choice of the gauge Boson Y(4) (4) for non-vanishing J(4), according to (6.22), (6.23) with the same as for N = 3 case interpretation for the modified Ward identities for the Green functions. Due to (6.26) for constant r, the usual G(4)-quartet of the Ward identities (4.14) for Z4|Y(4) (J(4)) follow from the first order in r.
Then, taking account of (6.23), we find that (6.26) implies a relation which describes the gauge dependence of Z4|Y(4) (J(4)) for a finite change of the gauge, Y(4)  Y(4) + Y(4):

Z4|Y(4)+Y(4) (J(4)) = Z4|Y(4) (J(4))

6.2 Gauge-independent Gribov-Zwanziger model with local N = 3, 4 BRST symmetries

Finally, we turn to the Gribov copies problem [8] within the GribovZwanziger model [36] with a gaugeinvariant horizon functional, H(Ah), recently proposed to be added to an N = 1 BRST invariant Yang
Mills quantum action [37] in Landau gauge with the use of the gauge-invariant (thereby, invariant with
respect to a local N = 1, 2 BRST invariance, as it was shown in [39], Eq. (36)(40)) transverse fields Ah = (Ah)ntn [43]:

(6.29)

Note, that the systematic study for the original GribovZwanziger model [36] with not BRST-invariant horizon, H(A), within Lagrangian BRST quantization of gauge theories [44], [45] from the viewpoint of

32

so-called soft BRST symmetry breaking was initiated in [46]. Then, as in the case of N = 1, 2 BRST symmetry, the gauge and N = 1, 2 BRST invariant extension of the respective quantum YangMills action within the R-family of gauges with a gauge fermion  and a boson Y prescribed by the Gribov Zwanziger actions are given by

As in the case of the N = 1, 2 BRST symmetry, one may expect the unitarity of the theory within the suggested N = 3, N = 4 BRST symmetry generalizations of the FaddeevPopov quantization rules [3]. These problems are under study.
The same results concerning the problems of unitarity and gauge-independence may be achieved within the local formulations of GribovZwanziger theory [36] when the horizon functional is localized (in the path integral) by means of a quartet of auxiliary fields aux = m  n, m  n; mn, m  n , having opposite Grassmann parities, (, ) = (, ) + 1 = 0, and being antisymmetric in su(N^ ) indices m, n. We suggest here the only N = 1 BRST invariant formulation,

S^GZ (1), aux = S0(A) +  (1) -s + S(Ah, aux).

(6.34)

S = ddx m  nM ml(Ah)ln - mnM ml(Ah)ln

+ f mnl(Ah)m(nl - nl) + 2d(N^ 2 - 1) ,

(6.35)

with additional non-local N = 1 BRST transformations for the fields aux with untouched ones for (1) (2.7)

aux-s = m  n, m  n; mn, m  n -s = 0, mn; m  n -  M -1 mk(Ah)f knl(Ah)l, 0 . (6.36)
The part S in case of N = 3 and N = 4 BRST formulation for the quantum actions (as well as for the N = 2 case) should be modified due to another spectra for the auxiliary fields aux.
Finally, the non-local gauge-invariant transverse fields, Ah, (6.28) can also be localized by using complex SU (N^ )-valued auxiliary field, h(x), with non-trivial own gauge and N = 1 BRST transformations [47] in order to reach really localized Gribov-Zwanziger model still N = 1, 2, 3, 4 BRST invariant without Gribov ambiguity, whose properties are now under study.

7 On Feynman diagrammatic technique in N = 3, N = 4 BRST quantization
Here, we introduce some new definitions to develop a Feynman diagrammatic technique for the Yang Mills theory within suggested N = 3 and N = 4 BRST invariant formulations for the non-renormalized quantum actions S(3) (3) given by (2.78)(2.81), and SY(4) (4) determined by (4.7)(4.10). To be complete, we compare the graphs which contain additional lines related to new fictitious fields to ones with
33

known, i.e. ghost, C(x), antighost, C(x), fields in N = 1 BRST setup and with duplet of ghost-antighost fields, Ca(x), a = 1, 2 in N = 2 BRST setup, having in mind that usually the Nakanishi-Lautrup field B(x) is integrated out from the quantum actions.
We present the generating functionals of Green functions in R-gauges Z(J) (2.9), ZY (J) determined
with the quantum action SY () (2.18), Z3| (J ) (2.74), Z4|Y (J(4)) (4.2) respectively for N = 1, 2, 3, 4 BRST symmetry within the perturbation theory according to [48] but for d-dimensional space-time

Note, starting from the N = 2 case we have introduced the additional notation of the respective (being valid for free (quadratic) theory) averaging fields 0 written under the respective propagator's line to distinguish different fictitious fields corresponding, in fact, to the same function, D(p). From the N = 3 case the propagator's line for the Grassmann-even (Bose) fictitious particle is given by "dash with dot" as compared to the standard "dash" notations for the Grassmann-odd (Fermi) fictitious particle. There are 3 independent propagators for Grassmann-odd fields among CpBqr 0 and 3 ones for Grassmann-even from BpBqr 0 in the Figure 3, which are C1B23 0, C2B31 0, C3B12 0 and B1B23 0, B2B31 0, B3B12 0, i.e. for {p, q, r}={(1, 2, 3); (2, 3, 1).(3, 1, 2)}. For N = 4 BRST symmetric case the Figure 4 contains 4 independent propagators for Grassmann-odd fields - Cr4B[r]3 0 and 3 ones for Grassmann-even from Br1r2 Br3r4 0: C1B234 0, C2B314 0, C3B124 0, C4B132 0 and B12B34 0, B13B42 0, B14B23 0.
There exist more additional vertexes from (7.9), (7.10), (7.11) which can be analogously represented as in the Figures 5, 6.
8 Conclusion
In the present work a generalization of the FaddeevPopov proposal presenting the Lagrangian path integral for the YangMills theory in Landau and Feynman gauges [3], [9] is proposed for non-local form by inserting the special unity, detkM (A) det-kM (A), depending on non-negative integer k in (2.31),

(2.32) and for local form in (2.33), with numbers of fictitious Grassmann-odd and Grassmann-even fields

(with the same number of physical degrees of freedom as compared to the case of space-time extended

SUSY gauge theories) in the spectrum of the total configuration spaces larger than those for N = 1, 2

BRST symmetry cases. It is shown in the Statement 1, that to realize the N = m BRST symmetry

transformations with more than two Grassmann-odd parameters, p, p = 1, 2, ..., m (in substituting instead of the infinitesimal gauge parameters  = Cpp the m-plet of Grassmann-odd ghost fields) when formulating the corresponding quantum actions, S(LN(k))((N(k))) (2.36) with the gauge-fixing terms
(respecting N (k) = m BRST invariance) to be added to the classical YangMills action the spectrum

of k = k(N ) should obey to the relation (2.38), whereas to perform the gauge-fixing procedure without

using an odd non-degenerate transformation changing the Grassmann parities for some fictitious fields

its spectrum k = ku(N ) is described by (2.39).

An irreducible representation space, commuting generators -s p with triplet

M(m3i)n, for the 3-parametric abelian superalgebra of Grassmann-odd constant parameters, p, with

G(3) of antiits action on

the local coordinates, fields (3), has been explicitly constructed by Eqs. (2.45). To formulate a local

quantum action with appropriate gauge-fixing procedure, we have followed two ways. First, that proves

the condition (2.38) of the Statement 1, is based on the original using of Grassmann-odd non-degenerate

operator  which changes the Grassmann parities and acts on G(3)-irreducible space of initial YangMills

fields A, triplets Cp, Bpq, odd singlet B, in such a way, that the respective change of variables in the

subspace of part of fictitious fields, M (A.8) has permitted to make possible to pass to a new basis of

fictitious fields in which the local quantum action (A.22) and path integral (A.13) in Landau gauge with

a new form of N = 3 BRST symmetry transformations, (A.23)(A.28), have been constructed. Second,

the non-minimal sector of the fields (3) containing antighost field (as a connection) C to incorporate the usual gauge condition, (A, B), into a gauge fermionic functional (3) (2.75) has been introduced, on which a new N = 3 representation of G(3)-superalgebra is explicitly realized (2.69). The sector contains

two G(3)-singlets, C, B with usual Nakanishi-Lautrup field and two G(3)-triplets, Bp, Bpq and together

37

with the fields, (3) composes the fields (3) of reducible G(3)-superalgebra representation parameterizing the total configuration space M(to3t), on which the quantum action S(3) (3) (2.78)(2.81) and path in-

tegral Z3|(0) (2.73) in R-like gauges, determined by the gauge fermionic functional (3) (3) (2.75), have been explicitly constructed. The set of the transformations in M(to3t), (3) = (3)-s pp, determined by (2.45), (2.69), leaving both the quantum action and the integrand of the respective path integral by

invariant,we call N = 3 BRST transformations. The quantum (non-renormalized) action S(3) contains the terms quadratic in fictitious fields leading to the same one-loop contribution for the effective action

as one for the quantum actions constructed according to N = 1 and N = 2 BRST symmetry principles

in smaller configuration space, whereas for more than quadratic in powers of ghost fields terms in S(3) , described by the Sadd(3) (2.81) which generates the ghost vertexes to be different than ones derived from
the former actions. We have established with the help of G(1)-superalgebra with nilpotent generator -s and parameter 

being additional to G(3)-superalgebra, but acting on the fields of M(to3t) by the rule (3.1), the fact that the G(1)- invariant path integral Z1|(0) (3.7) with the quantum action S(1) and, at least for special quadratic gauge fermionic functional (1) (3.8) given on M(to3t) is equivalent to the N = 1 antiBRST invariant path integral (3.12) with the quantum action S, (3.13) constructed by the standard Faddeev-Popov method
with use of N = 1 antiBRST symmetry transformations acting in the standard configuration space, Mtot of fields A, C, C, B. We call the transformations (3.9) with parameter  which led to the G(1)- invariance of S(1) and integrand of Z1|(0) by N = 1 antiBRST symmetry transformations in M(to3t).

It was shown the Grassmann-odd parameters: G(3)-triplet p and G(1)-singlet , of G(3) and G(1)

superalgebras acting on the space p,  , as well as the quartet of

R-like family of gauges determined by the functional Y(04)((4)) (4.6) the quantum action SY(4) (4)

(4.7) was exactly calculated for the Landau gauge ( = 0), whereas for the Feynman gauge ( = 1)

the additional summand Sadd(4) (4.10) to the standard gauge-fixed and quadratic [in 4 Grassmann-odd (C1, B234), (C2, B134), (C3, B124), (C4, B123) and 3 Grassmann-even (B12, B34), (B13, B24), (B14, B23)

pairs of ghost fields] parts Sgf(4), Sgh(4) of the quantum action contains the 8-th powers in odd Cr and 4-th power of even Br1r2 fields. For any  classical action and the functionals Sgf(4), Sgh(4) lead to the same contribution into one-loop effective action as those for the known and above quantum actions

constructed according to the N = 1, N = 2 and both N = 3 BRST symmetry recipes. It was explicitly

shown on the level of the non-renormalized path integrals the equivalence among N = 3 BRST invariant

path integral evaluated in the R-like gauges and usual N = 1 BRST invariant path integral in the R

-gauges in (2.94). For N = 4 BRST invariant path integral its equivalence with N = 1 BRST invariant

path integral was found in case of Landau gauge in (4.13).

For both N = 3 and N = 4 BRST invariant formulations of the quantum actions the generating functionals of Greens functions, including effective actions were determined and Ward identities (2.91), (4.14) for them, which follow from the respective algebraic N = m, m = 3, 4 BRST invariance, were derived as well as the independence on the choice of the gauge condition for the respective path integral under the corresponding small variation of the gauge: (3)  (3) + (3) and Y(4)  Y(4) + Y(4) were established by means of infinitesimal FD N = m BRST transformations.

38

The finite N = 3 and N = 4 BRST transformations were restored to form respectively the Abelian supergroups G(m) = exp{-s pp}, p = 1, 2, ..., m acting on the respective configuration space M(tomt) by means of two ways: first, by continuation of the invariance of any regular functional under algebraic

N = m, m = 3, 4 BRST transformations to full invariance under finite transformations, second by means of resolution of the Lie equations. The sets G~(m) (5.4), (5.22) of finite FD N = m BRST transfor-

mations were introduced and the respective Jacobians of the change of variables in M(tomt) generated by

these transformations were calculated in (5.5), (5.23). For functionally-dependent Grassman-odd parame-

odd(even) for m = 3 (m = 4) (5.11), (5.24) the Jacobians above are transformed to the respective

N = m BRST exact terms (5.12), (5.25). The latter Jacobians were applied, first, to the establishing

of the independence upon the choice of the gauge condition for finite variation of the respective path

integral, Z3|(3) (0) = Z3|(3)+(3) (0), Z4|Y (0) = Z4|Y +Y  (0), from the solutions of the corresponding compensation equations (6.2), (6.21) relating the parameters ^p1 with respective change of the gauge condition (3), Y(4) in (6.4) and (6.23). Second, they were used to derive new modified Ward identities

(6.8), (6.26) for the generating functionals of Green functions Z3|(3) (J(3)), Z4|Y(4) (J(4)) depending on the functionally-dependent FD parameters ^p1 , p1 = 1, 2.., m, and therefore on the finite variation of the
gauge (3), Y(4) respectively. Third, they have permitted to establish gauge independence of Z3|(3) (J(3)), Z4|Y(4) (J(4)) upon the respective choice of the gauge condition (3)  (3) + (3) and Y(4)  Y(4) + Y(4)

on the corresponding mass-shell: J(3) = 0, J(4) = 0.

The new Ward identities (6.19) for the extended (by means of sources Kp, Kpq, K to the N = 3 BRST variations (3)-s p, (3)-s p-s q, and (3)(-s )3) generating functional of vertex Green's functions,  (3) , Kp, Kpq, K (6.17) obtained from the part of extended N = 3 BRST transformations (6.12) in the space of (3), Kp, Kpq, K for constant p, reproduced the new differential-geometric objects. i.e., G(3)-triplets of antibrackets: (, )p and odd-valued first-order differential operators V p (6.20).

The gauge-independent Gribov-Zwanziger model of YangMills fields without residual Gribov ambiguity in the infrared region of the field A configurations described by gauge-invariant, and therefore N = m BRST invariant, for m = 3, 4, horizon functional H(Ah) (6.29) in terms of gauge-invariant transverse fields Ah (6.28) [43], firstly proposed in [37] within N = 1 BRST symmetry realization but with non-local BRST transformations was suggested in non-local form but with local N = 3, N = 4 BRST
invariance by the Eqs. (6.32), (6.33). The partially local, (in view of residual presence of non-local vector field Ah) Gribov-Zwanziger model was proposed with non-local N = 1 BRST symmetry (2.7), (6.36), due to inverse gauge-invariant Faddeev-Popov matrix M -1 (Ah) presence for auxiliary fields in (6.36).

The extension of the basics for the diagrammatic Feynman technique within perturbation theory for the N = 3 and N = 4 BRST invariant quantum actions for the YangMills theory were proposed due to the presence of additional both Grassmann-odd and Geassmann-even fictitious fields.

Concluding, let us present the spectrum of irreducible representations for a G(l) Abelian superalgebra

with l = 0 (non-gauge theories), l = 1 (BRST symmetry algebra), l = 2 (BRST-antiBRST symmetry

algebra), l = 3 (superalgebra with 3 BRST symmetries), and so on according to the chain (2.41)

(2.43), by a numeric pyramid partially similar to the Pascal triangle (1), which contains in its left-

hand side the symbol "d|A" relating to number of degrees of freedom of the classical YangMills fields

A with suppressed su(N^ ) indices: where an l-th row, corresponding to the field content (l) of an

irrep space for the G(l) superalgebra, is constructed from the symbols of d|A, l|C[r]1, C2l |B[r]2..., 1|B(l)

(Clk = k!/(l!(k - l)!)), corresponding to the degrees of freedom (modulo the dimension of su(N^ )) for A, Cpl , Bplql , ..., B(l), pl = 1, 2, ..., l, whose sum is equal to (2l + d - 1). The symbols related by an arrow:

In turn, for the reducible representation space of G(2K - 1)-superalgebra, for integer K determining the non-minimal sector of fields to be necessary to provide gauge-fixing procedure without odd supermatrix, the spectrum of additional fields is described by the Table 2 corresponding to the exact sequence (2.71). In particular, from Table 1 it follows that, for odd numbers N = 2K - 1 of parameters in the G(N ) superalgebra, the generalized FaddeevPopov rules must be described by odd non-degenerate transformation, , intended to present the path integral with the Grassmann-even NakanishiLautrup field B(2K-1) = B2k-1 exponentiating the standard gauge condition, added to the classical action using an N = (2K - 1) BRST-exact form.
It follows from the both Tables that the generalization of the Faddeev-Popov quantizations for the case of N = 2K - 1 BRST invariance without using of an odd non-degenerate transformation, when formulating the local quantum action and path integral leads to the dimension of the total configuration space M(to2tK-1) to coinciding with the one for Mt(o2tK) realizing N = 2K BRST symmetry for the same purpose.
There are various directions to extend the results of the present study. Let us mention some of them. First, to develop the case of N = 3, 4 BRST symmetries transformations in a Yang-Mills theory as a dynamical system with first-class constraints in the generalized canonical formalism [49], [50], [51]. Second: to develop the case of N = 3, 4 BRST symmetry transformations for irreducible general gauge theories in Lagrangian formalism [44], including theories with a closed algebra of rank 1. Third: to generalize, in a manifest way, the FaddeevPopov rules in YangMills theories to the case of N = 2K - 1 and N = 2K, K > 2 BRST symmetry transformations in Lagrangian formalism and in generalized canonical formalism. Then, it is intended to examine the case of irreducible dynamical systems subject

to N = 2K - 1, N = 2K, K > 2 BRST symmetry transformations and to compare the results with superfield formulations with N BRST charges in [52]. Next, it is planned to consider an irreducible general gauge theory subject to N = 2K - 1, N = 2K K > 2 BRST symmetry transformations in the Lagrangian formalism. The problem of study of the renormalizability for the suggested N = 3, 4 BRST invariant formulations of the quantum actions so as to have completely renormalized respective effective actions remains a very important question, as well as adopting of the N = m, m = 2, 3, 4 BRST invariance to the renormalizability of N = 1 space-time super YangMills theory in terms of N = 1 superfields considered for N = 1 BRST symmetry in [53], [54] on the basis of preserving the gaugeinvariance, and, hence, the N = m BRST symmetry, regularization by higher-derivatives [55], recently developed for N = 2 superfield formulation of Abelian and super YangMills theories [56] on a basis of N = 2 harmonic superspace approach [57]. We intend to study these problems in forthcoming works.

A On N = 3 BRST invariant gauge-fixing in N = 3 irreducible superspace

Here, we will prove that it is impossible to perform N = 3 BRST invariant gauge-fixing procedure within the set of fields A(33) parameterizing the superspace of irreducible representation of G(3)-superalgebra without using of non-degenerate odd-valued change of variables among the components of (3) to explicitly
construct such a gauge-fixing.

Indeed, it is easy to see that in the basis of additional to A fields in A(33) = (A, Cp, Bpq, B) composing the irreducible representation space of G(3)-superalgebra, on which due to Lemma 1 the N = 3 SUSY

transformations is realized (2.45), there are no enough coordinates to reach a non-local FaddeevPopov

path integral (2.31) with preservation of the symmetry above. The terms in the functional S(L3)((3))

where F (A) may be interpreted as a Grassmann-odd analog of gauge conditions (2.6), (2.15) used in the N = 1, 2 BRST symmetry realizations for the quantum action, and therefore M F (A, x; y) should be
considered as a Grassmann-odd analog of the FaddeevPopov matrix (1.4).

A.1 Non-degenerate odd-valued change of fictitious fields

To provide a satisfactory description, we must deal neither with the appearance in Z0L of the -function (F ) from odd-valued functions, nor with the superdeterminant sdetM F (A) from an odd-valued matrix

M F (A)10, we may pass to another basis of auxiliary fields, (3), in the representation space M(3) of the N = 3 superalgebra G(3) with the same number of Grassmann-odd and Grassmann-even fields. To

this end, we introduce a non-degenerate transformation in M(3): (3)  (3) = (3), with unaffected YangMills fields A, ghost fields C1, C3, bosonic fields B13, and to be transformed fictitious fields M =
(B23, B12, C2, B), by introducing a Grassmann-odd non-degenerate matrix N = NMN (analogous to the odd supermatrix  = AB = (A, B) , () = 1, resulting from the odd Poisson bracket, (, ), calculations with respect to the field-antifield variables A in the field-antifield formalism [44], [45]), composed from the unit matrices 1(N^2-1) with suppressed su(N^ )-indices, as follows:

(A.8)

with the odd non-degenerate supermatrix , which turns the only fields of definite parity into new fields with the same properties but with opposite parity:  B23, B12, C2, B = C1, C3, B2, B , so that by definition, the property to be idempotent for  holds: 2 = 1. Notice that the separation of the (un)transformed fields in (3) is not unique for unaffected A. Note, that in the usual sense [11], [58] sdetN = 0.
The supermatrix N plays the role of an inverse for itself, which make it possible to express the initial fictitious fields N from (A.8) as functions of new fictitious fields N :

M = N MN N , (N ) = 1, because of N 2 = 14(N^2-1).

(A.9)

10If one attempts to exponentiate the non-local path integral (2.31) over M(3) = {A(33)} in the basis of, first, the auxiliary
fields {Cp, Bpq , B} by means of the one Lie-group G-valued field B12 from the triplet of Grassmann-even fields Bpq , to exponentiate (), second, the pair, C1, C2 from the triplet of Grassmann-odd fields Cp, to exponentiate det M , third, the
pair B13, B23 from Grassmann-even fields Bpq , and the remaining pair of Grassmann-odd fields, C3, B, to exponentiate, respectively, det-1M and detM , we get:

Z0L =

dA() det2M (A) det-1M (A) exp

i h S0(A)

=

i d(3) exp h SL((3)) ,

for SL((3)) = S0(A) + ddx tr (A)B12 + C1M (A)C2 + B23M (A)B13 + C3M (A)B .

However, to provide N = 3 BRST invariance of the local action SL((3)) for YangMills theory one must impose additional requirement: B12 = 0, being rather restrictive one.

42

A.2 N = 3 BRST-invariance and path integral in new fictitious fields

The following step is based on a definition of the gauge fermion F(3)0(A) with help of the odd matrix  in quadratic form consistent for the Landau gauge:

F(L3)0(A)

=

-

1 2

ddx tr

AA

=

1 2

ddx AmmnAn, for (F(L3)0) = 1.

(A.10)

Because the map  acts linearly, turning the points (with coordinates) in a fiber of the respective bundle
into the same points (with coordinates) in a fiber of another bundle, but with opposite parity, then the respective infinitesimal gauge for A and N (3) SUSY transformations for A(33) make by natural the properties:

A = (A)  A = (A) = D(A)Cpp,  = , D(A)Cp = D(A)Cp   A, Cp = A, Cp ,

(A.11) (A.12)

where the last relation maybe considered as the continuation of the commutativity property of  with partial derivative .
Now, we can write the path integral related to (2.31) in a local form, (2.33) for k = 1 with the action SF(L3)0 (A.5), fermionic functional F(L3)0, in terms of a new basis of {A(33)} for the representation space of the G(3) superalgebra, as follows:

Here the relations (2.82), (2.83), (A.11), (A.12) and (B.9) for Landau gauge (A) = 0 were used as well as the vanishing of the terms, Cp1 , Cp2 [p]3  0.

43

Note, first, the terms proportional to the (A) in (A.18) maybe easily elaborated by the rule

tr (A) B = mnn(A)Bm = n(A)mnBm = tr (A)B, tr (A) Bpq, Cr = tr (A) Bpq, Cr ,

(A.19) (A.20)

by virtue of the properties (A.11), (A.12). Second, the quadratic in the fictitious fields with Faddeev Popov matrix summands, we can present due to the same properties as follows:
tr M(A)Cq Bpr = tr BprM(A)Cq = tr BprM(A)Cq = tr (Bpr)M(A)Cq. (A.21)

Expressing the fields M in terms of M , according to the change of variables (A.8) in M(3), we get for the action SF(L3)0 (A.13)(A.15) with use of (A.19)(A.21) and with use of dual field B2 = -B13 = 132B13:

SF(L3)0  = S0(A) + ddx tr (A)B + C3M(A)C3 + C1M(A)C1 + B2M(A)B2

(A.22)

Here, the role of FaddeevPopov ghosts is a mixed one, in comparison with the initial basis of fictitious fields Cp, Bpq, B. For example, in the first row of (A.22) for the fields C, C, used within the original FaddeevPopov quantization as ghost and antighost fields, we have, respectively, C1, B23 and C3, B12.

Therefore, as far as the last condition in (A.12) holds true, the functional SF(L3)0  , with the gauge functional (A.10) which determines the path integral ZF(L3)0 (A.13) in the Landau gauge with a local quantum action solving the problem of generalization of the FaddeevPopov rules in the case of the
irreducible representation N = 3-parametric G(3) superalgebra.

The latter local action (as well as the measure d(3)) corresponding to the Landau gauge is invariant under N = 3 (therefore called as N = 3 BRST) transformations, which, at the algebraic level in a new basis of fields, A(33), are written with allowance for (2.45), (A.8), (A.9), as follows:

where we introduced the formal identification B2 = B2 to use the antisymmetry of: C[1B2] = C1B2 - B2C1 being inherited from one for C[1C2]11.
Thus, we see, that the preservation of the explicit N = 3 BRST symmetry for the quantum action S(L3)((3)) in the space of G(3)-irreducible representation M(3) requires the introduction of odd nondegenerate supermatrix N with destroying of G(3)-covariance of the fields (3) to get local path integral (A.13) with N = 3 BRST invariance (A.23)-(A.28).
This fact proves the validity condition (2.38) of the Statement 1 concerning gauge-fixing procedure for odd N .

B N = 4 BRST Invariant YangMills Action in R-like Gauges

In this Appendix, we present the details of calculations used in Section 4 to find N = 4 BRST invariant
quantum action (4.7)(4.10) and establish a correspondence between the gauge-fixing procedures in the
YangMills theory described by a gauge-fixing function (A, B) = 0 from the class of R-gauges in N = 1 BRST formulation and by a gauge-fixing functional Y(04) in the suggested N = 4 BRST quantization.

To calculate SY(4) (4) we have used the results of applications (2.82)(2.86), (2.87), (2.88), (3.3) adapted for N = 4 case, as well as the property (4.11) for differentiation of the product and commutator of any two functions by products of the generators -s p up to 4-th order.

(B.10)

so that to derive the quadratic in the fields B terms, which should determine the gauge-fixed action for the Feynman-like gauge it is sufficient to calculate the last summand above, because of, Bq1q2 -s r1-s r2 = q1q2r1r2B + o(B, C), according to N = 4 BRST transformations (3.20).

Let us find the action of the operators -s r1 [r]4 and -s r1 -s r2 [r]4 on Bq1q2 [q]4 :

where we have used the Fierz-like identities for the products of Levi-Civita tensors:

   q1q2r1r2 [r]4 q3q4r3r4 = 4[q]4 , and q1q2r1r2 [r]4 q3q4r3r4 [q]4 = 4  4!,

(B.14)

and its normalization (2.37), (3.31). Now, we are waiting that the first and second terms in (B.10) of the third and fourth orders in -s r
when acting on Bq1q2 will not produce new summands to the gauge-fixed and quadratic in the fictitious
fields parts of the action (4.7). Their role concerns only to exclude non-diagonal terms from the last
quantity in (B.10) given explicitly in (B.13). To justify the proposal let us show, that the terms linear in B in (B.13) are absent in SY(4) (4) (4.7). To do so we need the product of three antisymmetrized

Consider, e.g. the summand, B Bq1q2r1, Cr2 in (B.13). The only second term in (B.10) gives similar contribution from (B.15), so that their sum is equal to:

= 4! ddx tr B Bq1q2r1 , Cr2 + B Bq1q2r2 , Cr1 q1q2r1r2  0,

(B.16)

due to the antisymmetry in r1, r2 of, Bq1q2r2 , Cr1 q1q2r1r2 = - Bq1q2r1 , Cr2 q1q2r1r2 and the property for su(N^ )-valued functions with definite Grassmann parities:

tr F G, H = F m f mnl Gn Hl = tr F, G H = -tr G F, H (-1)(F )(G).

(B.17)

The checking that the remaining terms linear in B in (B.13) do not contribute in the quantum action (4.7) may be fulfilled analogously, but we leave out of the paper scope the proof of this fact.
