摘要
We calculate the two-loop pressure of a plasma of quarks and gluons at finite temperature and chemical potential using the hard thermal loop perturbation theory reorganization of finite temperature/density quantum chromodynamics. The computation utilizes a high temperature expansion through fourth order in the ratio of the chemical potential to temperature. This allows us to reliably access the region of high temperature and small chemical potential. We compare our final result for the leading-and next-to-leading-order hard thermal loop perturbation theory pressure at finite temperature and chemical potential with perturbative quantum chromodynamics calculations and available lattice quantum chromodynamics results.
