Open flavour charmed mesons in a quantum chromodynamics potential model

Open flavour charmed mesons in a quantum chromodynamics potential model

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...

Description
Summary: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.
