Abstract

The charmonium potential at non-zero temperature has been studied using gauge configurations with anisotropic lattices and 2+1 dynamical flavors of light sea quarks. We use the HAL QCD time-dependent method developed for the study of nucleon-nucleon potentials. To serve as input, local-extended charmonium correlators were calculated. The results are consistent with the expectation that the potential between heavy quarks should become deconfining at high temperatures.
