Study of semileptonic and nonleptonic decays of the $B_c^{-}$ meson

Abstract

We evaluate semileptonic and two--meson nonleptonic decays of the $B_c^{-}$ meson in the framework of a nonrelativistic quark model. The former are done in spectator approximation using one--body current operators at the quark level. Our model reproduces the constraints of heavy quark spin symmetry obtained in the limit of infinite heavy quark mass. For the two--meson nonleptonic decays we work in factorization approximation. We compare our results to the ones obtained in different relativistic approaches.
