Nonleptonic Two-Body Decays of the B_c Mesons inLight-Front Quark Model

摘要

We study exclusive nonleptonic two-body B_c→(D_((s)),η_c,B_((c))+ F decays with F (pseudoscalar or vector meson) factored out in the QCD factoriza-tion approach. The nonleptonic decay amplitudes are related to the product of me-son decay constants and the form factors for semileptonic B_c decays. As inputs in obtaining the branching ratios for a large set of nonleptonic Bc decays, we use the weak form factors for the semileptonic B_c→(D_((s)),η_c, B_((s))) decays in the whole kinematical region and the unmeasured meson decay constants obtained from our previous light-front quark model.
