Description
Using a non-relativistic potential model, we obtain the mass spectra, leptonic decay constants, and parameters of the Isgur-Wise function for the beauty and charm mesons. With the calculated quantities, we investigate purely leptonic decays of $B^+$, $B^{*}$, $B_c^+$, semileptonic decay modes ${B_{(s)}} \to {D_{(s)}}l\nu $ and ${B_c} \to {\eta _c}\ell \bar \nu $ for three lepton channels $e,\mu ,\tau$, and obtain the corresponding branching fractions. $\bar B_{(s)}^{} \to D_{(s)}^*l\bar \nu $ transitions are also studied. Our results are found to be in agreement with those obtained in the experimental and theoretical results.
