We present matching factors for Zq calculated perturbatively at the one-loop level with improved staggered quarks. We calculate Zq 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.
