# Thermodynamics of quark-gluon plasma at finite baryon density

## TL;DR

This paper investigates the thermodynamic properties of the quark-gluon plasma at finite baryon density using the Field Correlator Method, finding good agreement with lattice data and no signs of critical behavior up to 400 MeV.

## Contribution

It introduces a nonperturbative approach to study QGP thermodynamics at finite baryon density, incorporating Polyakov line and string tensions, expanding understanding beyond perturbative methods.

## Key findings

- QGP thermodynamics matches lattice data at $rac{1}{2}$ 400 MeV
- Pressure and sound velocity show no critical behavior in this region
- Nonperturbative FCM dynamics effectively describe baryon density effects

## Abstract

Properties of the quark-gluon plasma(QGP) in the presence of the baryon chemical potential $\mu_B$ are studied using the Field Correlator Method(FCM). The nonperturbative FCM dynamics includes the Polyakov line, computed via colorelectric string tension $\sigma^E(T)$ and the quark and gluon Debye masses, defined by the colormagnetic string tension $\sigma^H(T)$. The resulting QGP thermodynamics at $\mu_B \le 400$ MeV is in a good agreement with the available lattice data,both pressure and the sound velocity do not show any sign of a critical behavior in this region.
