Mass splittings and decay properties of B, Bs and Bc mesons in a Dirac formalism

In this paper, we investigate the mass spectra and decay properties of B, Bs and Bc mesons using the relativistic potential model with confining potential V-q(r) = 1/2 (1 + y degrees)(a(2)r + V-degrees). The calculated mass spectra of B, Bs and Bc accord to the findings of the experiments and other theoretical forecasts. Using the same parameters, we calculate possible radiative decay widths of V (ns)-> P(ns)y and P(ns)-> V (ns)y, n =1,2,3 and weak leptonic decay constants of B, Bs and Bc mesons. Our results, in most cases, generally agree with experimental and other theoretical predictions. Finally, we also investigate mixing parameters x(q), y(q) and x(q) for B degrees(q) -B degrees(q) (qcd, s) mesons, where our calculated values reasonably agree with the experiment.
