Abstract

We present results on the QCD equation of state, obtained with two different improved dynamical staggered fermion actions and almost, physical quark masses. Lattice cut-off effects are discussed in detail as results for three different lattice spacings are available now, i.e. results have been obtained oil lattices with temporal extent of N-tau = 4,6 and 8. Furthermore we discuss the Taylor expansion approach to non-zero baryon chemical potential by means of an expansion of the pressure. We use the expansion coefficients to calculate various fluctuations and correlations among hadronic charges. We find that the correlations reproduce the qualitative behavior of the resonance gas model below T-c and start to agree with the free gas predictions for T greater than or similar to 1.57T(c).
