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 , , , semileptonic decay modes and for three lepton channels , and obtain the corresponding branching fractions. transitions are also studied. Next, we apply the form factors for spin zero and spin one transitions of to calculate the nonleptonic branching ratios of , where P and V stand for the vector meson and the pseudoscalar meson, respectively. Our results are found to be in agreement with those obtained in the experimental and theoretical results.
