Thermodynamically Consistent Formulation of Quasiparticle Viscous Hydrodynamics

Abstract

A novel formulation of second-order relativistic viscous fluid dynamics based on the effective Boltzmann equation for quasi-particles with mediumdependent masses is briefly reviewed. The evolution equations for the shear and bulk dissipative corrections, and the corresponding transport coefficients, are presented. Resulting approach allows for thermodynamicallyconsistent incorporation of lattice QCD equation of state in the fluid dynamical framework.

Resummed Relativistic Dissipative Hydrodynamics

“…The resulting effective mass scaled by T extracted from continuum extrapolated Wuppertal-Budapest lattice data [21] is shown in Figure 1 (left panel) [18]. At high temperatures (T ∼ 0.6 GeV) the scaled mass is ∼ T in agreement with the expected high-temperature behavior of QCD [77].…”
