NPR determination of quark masses from the HISQ action
Andrew T. Lytle (for the HPQCD Collaboration)🇬🇧
Abstract
I report on a calculation of bilinear Z-factors needed for determining Z_m using non-perturbative renormalization (NPR) on n_f=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.
