Analysis of two-body charmed B meson decays in factorization-assisted topological-amplitude approach
Source PublicationPHYSICAL REVIEW D
Language英语
AbstractWithin the factorization-assisted topological-amplitude approach, we study the two-body charmed B meson decays B-u,B-d,B-s -> (DM)-M-(*), with M denoting a light pseudoscalar (or vector) meson. The meson decay constants and transition form factors are factorized out from the hadronic matrix element of topological diagrams. Therefore, the effect of SU(3) symmetry breaking is retained, which is different from the conventional topological diagram approach. The number of free nonperturbative parameters to be fitted from experimental data is also much less. Only four universal nonperturbative parameters chi(C), phi(C), chi(E) and phi(E) are introduced to describe the contribution of the color-suppressed tree and W-exchanged diagrams for all the decay channels. With the fitted parameters from 31 decay modes induced by b -> c transition, we then predict the branching fractions of 120 decay modes induced by both b -> c and b -> u transitions. Our results are well consistent with the measured data or to be tested in the LHCb and Belle-II experiments in the future. Besides, the SU(3) symmetry breaking, isospin violation and CP asymmetry are also investigated.
