Renormalization of domain-wall bilinear operators with short-distance current correlators

High Energy Physics - Lattice 2016-09-14 v1

Abstract

We determine the renormalization constants for flavor non-singlet fermion bilinear operators of M\"obius domain-wall fermions. The renormalization condition is imposed on the correlation functions in the coordinate space, such that the non-perturbative lattice calculation reproduces the perturbatively calculated counterpart at short distances. The perturbative expansion is precise as the coefficients are available up to O(αs4)O(\alpha_s^4). We employ 2+12+1-flavor lattice ensembles at three lattice spacings in the range 0.044--0.080~fm.
