Abstract

Abstract We examine the ratio of rates for B → Dπ − and for B → Dϱ − . Specifically, we look in the limit that the heavy quark masses are taken to infinity and assume that factorization holds for the nonleptonic decays. By assuming reasonable momentum distributions for the quarks inside the mesons, we are able to estimate the one-loop strong interaction corrections to the relation Γ ( B → Dϱ − Γ( B → Dπ −) = ( ƒ ϱ ƒ π ) 2 . These turn out to be quite small of order one percent.
