Open Flavour Charmed Mesons in a QCD Potential model

摘要

We modify the mesonic wavefunction by using a short distance scale r0 inanalogy with Hydrogen atom and estimate the values of masses and decayconstants of the open flavour charm mesons D, Ds and Bc within the framework ofa QCD Potential Model. We also calculate leptonic decay widths of these mesonsto study branching ratios and life time. The results are in good agreement withexperimental and other theoretical values.
