Description
For study of masses of the ground, orbitally and radially excited states of heavy-light $B$ and $B_S$ meson using Cornell potential with $\mathcal{O}(1/m)$ correction to the potential energy term. We have also incorporated the relativistic correction to the kinetic energy term of the Hamiltonian. The spin-hyperfine, the spin-orbit and the tensor interactions as well as the effect of mixing are employed to obtained the pseudoscalar, the vector, radially and orbitally excited states meson masses. Leptonic and radiative leptonic decay widths, their branching ratios, E1 transitions and the mixing parameters are also estimated in the present work.
