Useful ratios between two-body nonleptonic and semileptonic decays of B mesons

We compute important ratios between decay widths of some exclusive two-body nonleptonic and semileptonic B decays, which could be test of factorization hypothesis. We also present a summary of the expressions of the decay widths and differential decay rates of these decays, at tree level, including l = 0 (ground state), l = 1 (orbitally excited) and n = 2 (radially excited) mesons in the final state. From a general point of view, we consider eight transitions, namely H -> P, V, S, A, A', T, P(2S),V (2S). Our analysis is carried out assuming factorization hypothesis and using the WSB, ISGW and CLFA quark models.
