Dissipative phenomena in chemically non-equilibrated quark gluon plasma
The dissipative corrections to the hydrodynamic equations describing the evolution of energy-momentum tensor and parton densities are derived in a simple way using the scaling approximation for the expanding quark gluon plasma at finite baryon density. This procedure has been extended to study the process of chemical equilibration using a set of rate equations appropriate for a viscous quark gl...

متن کاملThermal rho’s in the quark-gluon plasma
I discuss different models which predict changes in the mass of the thermal ρ field. I emphasize that while the predictions are strongly model dependent, nevertheless substantial shifts in the thermal ρ mass are expected to occur at the point of phase transition. As long as the thermal ρ peak does not become too broad, this should provide a striking signature of the existence of a phase transit...
متن کاملHard Thermal Loops , Quark - Gluon Plasma Response
I outline various derivations of the non-Abelian Kubo equation, which governs the response of a quark-gluon plasma to hard thermal perturbations. In the static case, it is proven that gauge theories do not support hard thermal solitons. Explicit solutions are constructed within an SU (2) Ansatz and they are shown to support the general result. The time-dependent problem, i.e., non-Abelian plasm...
متن کاملStrangeness Production in Chemically Non-Equilibrated Parton Plasma
Strangeness production was investigated during the equilibration of a gluon dominated parton plasma produced at RHIC and LHC energies. The time evolution of parton densities are followed by a set of rate equations in a 1-dimensional expanding system. The strangeness production will depend on the initial chemical equilibration level and in our case the parton densities will remain far from the f...
