Effect of the gluon damping rate on the viscosity coefficient of the quarkgluon plasma at finite chemical potential
Abstract
By considering the Debye screening and the damping rate of gluons, the viscosity coefficient of the quarkgluon plasma was evaluated via realtime finite temperature QCD in the relaxation time approximation at finite temperature and chemical potential. The results show that both the damping rate and the quark chemical potential cause considerable enhancements to the viscosity coefficient of the hot dense quarkgluon plasma.
