Abstract
We compute the pressure of a finite-density quark-gluon plasma at zero temp erature to leading order in hard-thermal-loop perturbation theory, which in cludes 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 depen ding on mu.
