Transport coefficients of hot and dense matter in relativistic heavy-ion collisions

Abstract

The transport coefficients are known as the measure of system interactions, as well as the dynamical input of the hydrodynamic evolution equations of an expanding system created in the relativistic heavy ion collisions. In the current analysis, they have been evaluated for strongly interacting quark-gluon plasma system as well as hot hadronic media. The medium effects for an interacting QCD system have been introduced through a quasiparticle model. The same for a hadronic system has been captured via the in-medium self-energy correction using thermal field theory. The resulting behavior of the transport coefficients shows significant modification with respect to the estimations made in vacuum or using ideal equation of state.
