Abstract

We present a preliminary domain-wall fermion lattice-QCD calculation of isovector vector and axial charges, gV and gA, of the nucleon. Since the lattice renormalizations, ZV and ZA, of the currents are identical with DWF, the lattice ratio (gA/gV)lattice directly yields the continuum value. Indeed ZV determined from the matrix element of the vector current agrees closely with ZA from a non-perturbative renormalization study of quark bilinears. We also obtain spin related quantities Δq/gV and δq/gV.
