Abstract

We compute the next to leading QCD corrections to weak four fermion interactions introducing a scheme that does not require an explicit definition of γ5\gamma_5 in dd dimensions. This scheme reduces greatly the difficulties in calculating the two loop anomalous dimensions; we recover the results obtained in the previous literature.

Keywords
