Abstract

We study exclusive nonleptonic two-body Bc→(D(s),ηc,B(s))+F decays with F (pseudoscalar or vector mesons) factored out in the QCD factorization approach. The nonleptonic decay amplitudes are related to the product of meson decay constants and the form factors for semileptonic Bc 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 Bc→(D(s),ηc,B(s)) decays in the whole kinematical region and the unmeasured meson decay constants obtained from our previous light-front quark model. We compare our results for the branching ratios with those of other theoretical studies.
