Quasiparticle description of deconfined matter at finite mu and T

Abstract

An effective quasiparticle description of deconfined QCD thermodynamics compatible with both finite temperature nonperturbative lattice data and the asymptotic limit is generalized to finite chemical potential. Implications for the N_f = 4 flavor lattice data extended to mu \neq 0 as well as for deconfined matter with realistic quark masses are considered.
