We present a one-loop calculation of the renormalization constants of two-fermion local operators with the nearest-neighbour improved action. This calculation is a necessary ingredient in lattice computations of continuum hadronic matrix elements relevant for the predictions of many interesting physical quantities, including fπ,ρ, electromagnetic form factors, semi-leptonic D-decays, etc.

Abstract

We present a one-loop calculation of the renormalization constants of two-fermion local operators with the nearest-neighbour improved action. This calculation is a necessary ingredient in lattice computations of continuum hadronic matrix elements relevant for the predictions of many interesting physical quantities, including fπ,ρ, electromagnetic form factors, semi-leptonic D-decays, etc.
