Perturbative calculation of $Z_q$ at the one-loop level using HYP-smeared staggered quarks
May 29, 2019
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 using both RI-MOM and RI$'$-MOM schemes. We compare the results with those obtained using the nonperturbative renormalization (NPR) method.
