Abstract:
In this Letter we give the equation of state of QCD at finite temperatures and densities. The recently proposed overlap improving multi-parameter reweighting technique is used to determine observables at nonvanishing chemical potentials. Our results are obtained by studying n(f) = 2 + 1 dynamical staggered quarks with semi-realistic masses on N-t = 4 lattices. (C) 2003 Elsevier B.V. All rights reserved.
