We compute the next-to-leading-order QCD corrections to weak four-fermion interactions, introducing a scheme that does not require an explicit definition of gamma5 in d dimensions. This scheme greatly reduces the difficulties in calculating the two-loop anomalous dimensions; we recover results obtained in the literature.

Abstract
We compute the next-to-leading-order QCD corrections to weak four-fermion interactions, introducing a scheme that does not require an explicit definition of gamma5 in d dimensions. This scheme greatly reduces the difficulties in calculating the two-loop anomalous dimensions; we recover results obtained in the literature.File in questo prodotto:
