Heavy-light Mesons in a QCD Potential model with relativistic effect    [PDF]

Krishna Kingkar Pathak, D K Choudhury, N S Bordoloi

We study the masses and decay constants of heavy-light flavour mesons D, Ds, Bd and Bs in a QCD Potential model. We use the mesonic wavefunction in momentum space and estimate the pseudoscalar decay constants. We also calculate leptonic decay widths of these mesons to compute the leptonic branching ratio for different leptonic channels. The results are found to be compatible with available data.
