Decay properties of heavy quarkonia employing Cornell potential

Quarkonia are the mesonic states having both the quark of the same type and out of which heavy quarkonia refer to the bound state of charm and/or bottom quark. These flavorless mesons are one of the very important tool to understand the strongly interacting systems. The various theoretical models have successfully computed the mass spectra of heavy quarkonia however many decay properties computations are still deviating from the experimental data. Recently, we have studied the mass spectra and weak decay properties of charmonia, bottomonia and Bc mesons. For computation of mass spectra, we consider the interacting potential between quark and antiquark of the form Cornell potential
