Lattice renormalization of O(a) improved heavy-light operators

The analytical expressions and the numerical values of the renormalization constants of O(a) improved static-light currents are given at one-loop order of perturbation theory in the framework of heavy quark effective theory: the static quark is described by the HYP action and the light quark is described either with the Clover or the Neuberger action. These factors are relevant to extract from a lattice computation the decay constants f{sub B}, f{sub B{sub S}} and the set of bag parameters B{sub i} associated with B-B mixing phenomenology in the standard model and beyond.
