Study of exclusive semileptonic and nonleptonic decays of $B_c^{-}$ in a nonrelativistic quark model

Abstract

We present results for different observables measured in semileptonic and non-leptonic decays of the $B_c^{-}$ meson. The calculations have been done within the framework of a nonrelativistic constituent quark model. In order to check the sensitivity of all our results against the inter-quark interaction we use five different quark--quark potentials. We obtain form factors, decay widths and asymmetry parameters for semileptonic $B_c^{-}\to c\bar{c}$ and $B_c^{-}\to \bar{B}$ decays. In the limit of infinite heavy quark mass our model reproduces the constraints of heavy quark spin symmetry. For the actual heavy quark masses we find nonetheless large corrections to that limiting situation for some form factors. We also analyze exclusive non-leptonic two--meson decay channels within the factorization approximation.
