Description

We calculate thermodynamic potential at finite temperature and finite baryon chemical potential of a system of quarks and gluons using three-loop hard-thermal-loop perturbation theory. This is the highest order accessible by finite temperature perturbation theory applied to a non-Abelian gauge theory before the high-temperature infrared catastrophe. We compare the resulting pressure and diagonal quark number susceptibilities with available lattice data. We find reasonable agreement between our analytic results and lattice data at both zero and finite chemical potential. We further calculate other thermodynamical quantities like trace anomaly, speed of sound etc. both at zero as well as finite chemical potential and we get good agreement with lattice data.
