Background gauge renormalization and BRST identities

arXiv:1801.01098 · doi:10.1016/j.aop.2017.12.014

Abstract

We show that the BRST identities can be used to control the renormalization of the background gauge in QCD, in spite of the fact that one-particle reducible graphs have to be omitted. We obtain the all orders renormalized affective action for the background field theory.
