We calculate one-loop renormalization factors for heavy-light bilinears as
well as four-fermion operators relevant for $B^{0} - \bar{B}^{0}$ 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.
