Charmonium Potentials at Finite Temperature

Understand

The charmonium states at non-zero temperature are studied on anisotropic lattices with 2 dynamical quark flavours.

• Non-local operators are used to determine the Nambu-Bethe-Salpeter (NBS) wavefunctions via both conventional fitting methods and the Maximum Entropy Method.
• The interquark potential is determined from the solution of the Schrodinger equation, given the NBS wavefunction as input following the HAL QCD method.
• We observe a temperature dependent potential which becomes steeper as the temperature decreases.
