Influence of Width from Landau Damping on the Thermodynamic Potential in Quark-Gluon-Plasma

By considering the Debye screening and the finite width of soft gluons,the effective two-loop thermodynamic potential in quark-gluon plasma was evaluated via real-time temperature quantum chromodynamics.The result that depends on damping rate of soft transverse gluons as a physical parameter is obtained,and extension of the case including the longitudinal gluon and fermion will be straightforward.
