Contribution

It generalizes an effective quasiparticle description to include finite chemical potential, bridging lattice data and theoretical limits.

Findings

Model agrees with lattice data at finite mu and T

Provides insights into deconfined matter with realistic quark masses

Extends understanding of QCD thermodynamics beyond zero chemical potential

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.
