Mass spectra of B, B_s mesons using Dirac formalism with martin-like confinement potential

The predictions of masses of heavy-light system for low-lying states of these open beauty mesons thus become important from the point of view of understanding the behaviour of quantum chromodynamics at this hadronic scale. More over, these are open flavour beauty mesons, their decays are dominated by weak interaction processes and are free from interference due to strong interaction processes. Thus the complete understanding of the spectroscopy and decay properties of these open flavour mesons becomes very important. Though there exist theoretical predictions for the low lying states of B, B_s mesons, their excited state predictions in view of the new observations in the energy range 5-6 GeV become topics of current interest. Here we study the mass spectra of B and B_s mesons in a relativistic framework
