Abstract:
We generalize the superfield BRST quantization method for general gauge theories to the case of gauge fixing by the corresponding generating equation. We find a superfield form of the BRST symmetry of the vacuum functional and prove the gauge independence of the S-matrix. We show that the vacuum functional of the BV quantization method corresponds to a particular solution of the gauge-fixing generating equation. We discuss a modified version of the Ward identities related to the proposed generalized procedure of gauge fixing.
