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.
