BRST gauge fixing and regularization
Abstract
In the presence of consistent regulators, the standard procedure of BRST gauge fixing (or moving from one gauge to another) can require nontrivial modifications. These modifications occur at the quantum level, and gauges exist which are only welldefined when quantum mechanical modifications are correctly taken into account. We illustrate how this phenomenon manifests itself in the solvable case of twodimensional bosonization in the path integral formalism. As a byproduct, we show how to derive smooth bosonization in BatalinVilkovisky Lagrangian BRST quantization.
