Two-bodyBc→D(s)(*)P,D(s)(*)Vdecays in the perturbative QCD approach
2012
Physical Review D
We make a systematic investigation on the two-body nonleptonic decays B_c → D^(*)_(s)P, D^(*)_(s)V, by employing the perturbative QCD approach based on k_T factorization, where P and V denote any light pseudoscalar meson and vector meson, respectively. We predict the branching ratios and direct CP-asymmetries of these B_c decays and also the transverse polarization fractions of B_c → D^*_(s)V decays. It is found that the non-factorizable emission diagrams and annihilation type diagrams have
