Description

We present matching factors for $Z_q$ calculated perturbatively at the one-loop level with improved staggered quarks. We calculate $Z_q$ with HYP-smeared staggered quarks and Symanzik-improved gluons in RI- and RI$'$-MOM scheme. Using the conversion factor, we also present $Z_q$ in MSbar scheme. As a byproduct, we present the quark mass renormalization factor $Z_m$ in MSbar scheme. We compare the result from this work with those of nonperturbative renormalization method.
