Speed of sound in quark gluon plasma with one loop correction in mean field potential

TL;DR

This paper investigates the thermodynamic properties and speed of sound in quark-gluon plasma, incorporating one loop corrections in the mean-field potential, and finds results consistent with lattice QCD calculations.

Contribution

It introduces a one loop correction in the mean-field potential to analyze thermodynamics and sound speed in QGP, aligning theoretical predictions with lattice results.

Findings

Speed of sound squared C2s ≈ 0.3, independent of loop correction parameters

Thermodynamic properties match recent lattice QCD results

Results validate the mean-field approach with loop corrections in QGP

Abstract

We study thermodynamic properties and speed of sound in a free en- ergy evolution of quark-gluon plasma (QGP) with one loop correction factor in the mean-field potential. The values of the thermodynamic prop- erties like pressure, entropy and specific heat are calculated for a range of temperatures. The results agree with the recent lattice results. The speed of sound is found to be C2 s = 0.3 independent of parameters used in the loop correction which matches almost with lattice calculations.
