First order dissipative hydrodynamics and viscous corrections to the entropy four-current from an effective covariant kinetic theory

Abstract: The first order hydrodynamic evolution equations for the shear stress tensor, the bulk viscous pressure and the charge current have been studied for a system of quarks and gluons, with a non-vanishing quark chemical potential and finite quark mass. The first order transport coefficients have been obtained by solving an effective Boltzmann equation for the grand-canonical ensemble of quasiquarks and quasigluons. We adopted temperature dependent effective fugacity for the quasiparticles to encode the hot QCD med… Show more

“…where μν = g μν − u μ u ν is the projection operator orthogonal to the fluid velocity u μ and g μν = diag(1, −1, −1, −1) is the metric tensor. It is established that the dynamics of the bulk QGP is sensitive to the viscous transport (both shear and bulk viscosity) of the medium [50][51][52]. The stress tensor and bulk-viscous pressure satisfy relaxation-type equations as follows [53][54][55]:…”
