Quintero Física, Astronomía y Matemáticas B physics nonleptonic decays semileptonic decays 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 0; T; P(2S); V (2S). Our analysis is carried out assuming factorization hypothesis and using the WSB, ISGW and CLFA quark models. 2011 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57024209010 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
