The nonleptonic decays B+c→D+sD0 and B+c→D+sD0 in a relativistic quark model

In the wake of exploring CP-violation in the decays of B and Bc mesons, we perform the straightforward calculation of their nonleptonic decay rates within a relativistic quark model. We confirm that the decays Bc→DsD0 and Bc→DsD0 are well suited to extract the Cabibbo–Kobayashi–Maskawa angle γ through the amplitude relations because their decay widths are the same order of magnitude. In the b–c sector the decays B→DK and Bc→DD lead to squashed triangles which are therefore not so useful to determine the angle γ experimentally. We also determine the rates for other nonleptonic Bc-decays and compare our results with the results of other studies.
