Charge radii of heavy flavored mesons in a potential model

Abstract

We report the results for charge radii of heavy flavored mesons ($D^{+},D^0,D_s^{+},B^{+},B^0,B_s^0$) in an improved QCD potential model. To enhance the effectiveness of short range and long range effect of the potential $V(r)=-4\frac{{\alpha }_s}{3r}+br+c$ in the perturbative procedure a cut-off parameter $r^P$ is introduced as an integration limit. The obtained results are found to be comparable with other available data. The limitation of the approach is discussed in the manuscript.
