Relativistic correction to charmonium dissociation temperature

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/ψ dissociation temperature determined by the infinity size or zero binding energy of the system increases 7%-13%, when the central potential varies between the free energy and internal energy.
