Quasiparticle Description of Hot QCD at Finite Quark Chemical Potential
Abstract
We study the extension of a phenomenologically successful quasiparticle model that describes lattice results of the equation of state of the deconfined phase of QCD for Tc <= T < 4 Tc, to finite quark chemical potential mu. The phase boundary line Tc(mu), the pressure difference (p(T,mu)-p(T,mu=0))/T4 and the quark number density nq(T,mu)/T3 are calculated and compared to recent lattice results. Good agreement is found up to quark chemical potentials of order mu = Tc.
