Effect of flow on the quasiparticle damping rate in hot QCD plasma    [PDF]

Sreemoyee Sarkar, Abhee K. Dutt-Mazumder

We derive an expression for the quark damping rate in hot quark gluon plasma in presence of flow. Unlike earlier treatments here all the bath particles are out of equilibrium due to the existence of non-zero velocity gradient. The quasi particle damping rate is found to be finite once the hard thermal loop (HTL) corrected gluon propagator is used.
