Nucleon isovector charges from physical mass domain-wall QCD

Systematics in nucleon isovector vector, g_V, and axialvector, g_A, charges calculated on a 2+1-flavor dynamical domain-wall-fermions (DWF) ensemble at physical mass jointly generated by RIKEN-BNL-Columbia (RBC) and UKQCD Collaborations with lattice cut off of 1.730(4) GeV, are analyzed. Both are calculated with about a percent or less statistical errors. A... Show more
