A Note on Slavnov-Taylor Identities in the Causal Epstein-Glaser Approach

High Energy Physics - Theory 2015-06-26 v1

Abstract

An alternative approach to perturbative Yang-Mills theories in four (3+1) dimensional space-time based on the causal Epstein-Glaser method in QFT was recently proposed. In this short note we show that the set of identities between C-number distributions expressing nonabelian gauge invariance in the causal approach imply identities which are analogous to the well-known Slavnov-Taylor identities. We explicitly derive the Z-factor relations at one-loop level.
