We discuss perturbative O(g(2)a) matching with static heavy quarks and domain-wall light quarks for lattice operators relevant to B-meson decays and B-0-(B) over bar (0) mixing. The chiral symmetry of the light domain-wall quarks does not prohibit operator mixing at O(a) for these operators. The O(a) corrections to physical quantities are non-negligible and must be included to obtain high-precision simulation results for CKM physics. We provide results using plaquette, Symanzik, Iwasaki and DBW2 gluon actions and applying APE, HYP1 and HYP2 link-smearing for the static quark action.
