Description

We derive an expression for the heavy quark damping rate in hot quark gluon plasma in the presence of flow. All the bath particles in the present case are out of equilibrium due to the existence of nonzero velocity gradient. The magnetic sector exhibits similar infrared divergences even after hard thermal loop corrections as one encounters in the case of nonviscous plasma. We estimate the first order correction in $\eta/s$ for heavy quark damping rate due to the nonzero viscosity of the QCD plasma.
