Abstract
We compare our 2+1 flavor, staggered QCD lattice results with a quasiparticle picture. We determine the pressure, the energy density, the baryon density, the speed of sound and the thermal masses as a function of T and μB. For the available thermodynamic quantities the difference is a few percent between the results of the two approaches. We also give the phase diagram on the μB–T plane and estimate the critical chemical potential at vanishing temperature.
