NPR determination of quark masses from the HISQ action
Abstract
I report on a calculation of bilinear Z-factors needed for determining Zm using non-perturbative renormalization (NPR) on nf=2+1+1 HISQ ensembles. RI/MOM and RI/SMOM schemes are studied. These will provide an independent determination of quark masses in addition to other methods being used by the HPQCD collaboration.
