| Abstract: | We modify the mesonic wave function by using a short distance scale r 0 in analogy with hydrogen atom and estimate the values of masses and decay constants of the open flavour charm mesons D, D s and B c within the framework of a QCD potential model. We also calculate leptonic decay widths of these mesons to study branching ratios and lifetime. The results are in good agreement with experimental and other theoretical values. |
