Description

The QCD transition is studied on lattices up to Nt=16. The strange susceptibility the chiral condensate and the renormalized Polyakov loops are presented. The equation of state is determined on lattice with Nt-6,8,10 and at some temperature values with Nt=12. The pressure, the trace anomaly, the energy and entropy density and the speed of sound are presented as functions of the temperature in the range 100 ...1000 MeV . We give estimates for the pion mass dependence and for the contribution of the charm quark. We compare our data to the equation of state obtained by the "hotQCD" collaboration.
