Self-consistent quasiparticle model for 2, 3 and (2+1) flavor QGP

Abstract

Quasi-particle model of quark gluon plasma is the statistical mechanics of particles with medium dependent mass, related to plasma frequency, which was proposed to describe the thermodynamics of the medium itself. At relativistic limit the plasma frequency depends on number density and temperature. The number density is a thermodynamic quantity of the medium which in turn depends on plasma frequency. Hence, one need to solve this problem self-consistently, instead of using perturbative expressions for plasma frequency. Here we carry out such a self-consistent calculations using our, recently developed, a new formulations of quasiparticle model. By adjusting a single parameter for each system, a remarkably good fit to lattice QCD results are obtained for 2, 3 and (2+1) flavor quark gluon plasma systems, first, with zero chemical potential. Then, it is extended to systems with finite chemical potential and fits very well the lattice results without any new parameter.
