Temperature dependence of the static quark diffusion coefficient
Temperature dependence of the static quark diffusion coefficient
The propagation of a low momentum heavy quark in a deconfined quark-gluon plasma can be understood in terms of a Langevin description. The momentum exchange with the plasma in thermal equilibrium can then be parametrized in terms of a single heavy quark momentum diffusion coefficient κ, which needs to be determined nonperturbatively. In this work, we study the temperature dependence of κ for a static quark in a gluonic plasma, with a particular emphasis on the temperature range of interest for heavy ion collision experiments.

Abstract
The propagation of a low momentum heavy quark in a deconfined quark-gluon plasma can be understood in terms of a Langevin description. The momentum exchange with the plasma in thermal equilibrium can then be parametrized in terms of a single heavy quark momentum diffusion coefficient κ, which needs to be determined nonperturbatively. In this work, we study the temperature dependence of κ for a static quark in a gluonic plasma, with a particular emphasis on the temperature range of interest for heavy ion collision experiments.
