Abstract

We present a two-loop computation of the beta functions and the anomalous dimensions of a γ5\gamma_5-Yukawa model using differential renormalization. The calculation is carried out in coordinate space without modifying the space-time dimension and no ad-hoc prescription for γ5\gamma_5 is needed. It is shown that this procedure is specially suited for theories involving γ5\gamma_5, and it should be considered in analyzing chiral gauge theories.
