“…In Ref. [14] it was shown that the obtained thermal mass can be indeed used as an effective mass in the equation of state, comparing favorably with SU(2) lattice QCD data. Early (very poor) lattice data on the pressure and energy density of pure SU(3) gauge theory in the temperature region 1.2 < T /T c < 2.4 [15] were interpreted with a constant gluon mass, M g ≈ 500 MeV, and a constant bag constant B 1/4 ≈ 200 MeV [16].…”

We analyze recent results of SU(3) lattice QCD calculations with a phenomenological parametrization for the quark-gluon plasma equation of state based on a quasi-particle picture with massive quarks and gluons. At high temperature we obtain a good fit to the lattice data using perturbative thermal quark and gluon masses from an improved HTL scheme. At temperatures close to the confinement phase transition the fitted masses increase above the perturbative value, and a non-zero (but small) bag constant is required to fit the lattice data.

“…In quasiparticle models [14][15][16], a massive system of noninteracting quasiparticles is described where mass of these quasiparticles depend only on temperature. The quasiparticles acquire mass due to the interaction of quarks and gluons with the surrounding matter [20][21][22][23]. The effective mass of these quasiparticles is given by Ref.…”

Abstract. The equation of state (EoS) of quark-gluon plasma (QGP) using a phenomenological model is studied in which finite value of quark mass is modified as effective mass. The effective mass of these quasiparticle generated due to the interaction of quarks and gluons with the surrounding matter in the medium. The model results provide EoS of QGP which are in good agreement and found almost similar results to the earlier theoretical results. This model is successfully applied to the description of the properties of quark-gluon plasma created in the collision of nucleons. Thus, the effective mass of quark shows the useful information to study the EoS of QGP in high energy heavy-ion collisions.

“…A possible solution of this problem is to introduce notion of quasiparticles and consider temperature dependence of (now treated as effective) mass, m = m(T ) [6]. One should note that while at large-T limit of QCD the idea of quasi-particles may be physically sound (m ∼ T ) [7], at low temperatures (especially in the QCD phase-transition region), the quasiparticles do not correspond to any real excitations of the underlying theory.…”

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.
