Relativistic Correction to Charmonium Dissociation Temperature

Abstract

By solving the covariant relativistic Schrödinger equations for a pair of heavy quarks, we obtained the wave functions for the ground and excited quarkonium states at finite temperature. In comparison with the non-relativistic calculation, the $J/\psi$ dissociation temperature determined by the infinity size or zero binding energy of the system increases $7$, when the central potential varies between the free energy and internal energy.
