The QCD equation of state at nonzero densities: lattice result
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 nf=2+1 dynamical staggered quarks with semi-realistic masses on Nt=4 lattices.
