Perturbative renormalization for static and domain-wall bilinears and four-fermion operators with improved gauge actions
Abstract
We calculate one-loop renormalization factors for heavy-light bilinears as well as four-fermion operators relevant for

mixing calculations on the lattice. We use the static approximation for heavy quarks and the domain-wall formulation for light quarks. We present results for different choices of improved gauge action.
