Effect of smearing potential term on charmonium spectroscopy
Mass spectra and decay properties of Charmonia are computed in non-relativistic quark-antiquark Cornell potential model with additional smearing interaction. We have employed the non-relativistic numerical solution of Schr\"odinger equation for computing mass spectra. Further the confined one gluon exchange potential is employed perturbatively for computation of higher excited states. Various decay properties are computed using the model parameters and numerical wave functions.
