Nonperturbative gauge fixing and perturbation theory
Abstract
We compare the gaugefixing approach proposed by JonaLasinio and Parrinello and by Zwanziger (JLPZ) with the standard FaddeevPopov (FP) procedure, and demonstrate perturbative equality of gaugeinvariant quantities, up to irrelevant terms induced by the cutoff. We also show how a set of local, renormalizable Feynman rules can be constructed for the JLPZ procedure. Therefore the physical observables of the JLPZ and FP versions are equal to all orders up to a finite renormalization of the coupling constant.
