Abstract
We present a two-loop computation of the beta functions and the anomalous dimensions of a γ5 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 is needed. It is shown that this procedure is specially suited for theories involving γ5, and it should be considered in analyzing chiral gauge theories.Keywords
