Weak decays of the Bc meson to charmonium and D mesons in the relativistic quark model -: art. no. 094020

Semileptonic and nonleptonic decays of the B-c meson to charmonium and D mesons are studied in the framework of the relativistic quark model. The decay form factors are explicitly expressed through the overlap integrals of the meson wave functions in the whole accessible kinematical range. The relativistic meson wave functions are used for the calculation of the decay rates. The obtained results are compared with the predictions of other approaches.
