Thermodynamical Investigation of the Quark-Gluon Plasma Phase near the Deconfining Phase Transition

Abstract

We investigate, in the present work, some thermodynamical properties of a Quark-Gluon Plasma (QGP), near the thermal deconfining phase transition, at vanishing chemical potential. We project the QGP partition function onto the color-singlet SU(3) representation using a density of states once containing the volume term only, then containing the curvature and the volume terms, according to the Multiple Reflection Expansion approximation. We study the evolution of some physical quantities well describing the mixed hadronic gas-QGP system. We compare the present results to those obtained in our previous works.
