Abstract

We study exclusive non-leptonic two-body Bc(D(s),ηc,B(s))+FB_c\to(D_{(s)},\eta_c,B_{(s)})+F decays with FF(pseudoscalar or vector meson) being factored out in QCD factorization approach. The non-leptonic decay amplitudes are related to the product of meson decay constants and the form factors for semileptonic BcB_c decays. As inputs in obtaining the branching ratios for a large set of non-leptonic BcB_c decays, we use the weak form factors for the semileptonic Bc(D(s),ηc,B(s))B_c\to(D_{(s)},\eta_c,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 of the branching ratios with those of other theoretical studies.
