Hard-thermal-loop resummed pressure of a degenerate quark-gluon plasma

Abstract

We compute the pressure of a finite density quark-gluon plasma at zero temperature to leading order in hard-thermal-loop perturbation theory, which includes the fermionic excitations and Landau damping. The result is compared with the weak-coupling expansion for finite positive chemical potential $\mu$ through order ${\alpha }_s^2$ and with a quasiparticle model with a mass depending on $\mu$.
