Perturbative renormalization factors of quark operators for domain-wall QCD

Abstract: We calculate one-loop renormalization factors of several quark operators including bilinear, three- and four-quark operator for domain-wall fermion action. The calculation is done within Green functions constructed by physical quark fields. We show that our renormalization method is simple and can be easily applied to calculation of quark operators. We also include renormalization of axial current given by Shamir and Furman as an application. The general trend of our results is that these quark operators preserve several chiral properties of continuum massless QCD.
