【 摘 要 】

We report on a continuum extrapolated result [1] for the equation of state (EoS) of QCD with Nf 2 + 1 dynamical quark flavors and discuss preliminary results obtained with an addition dynamical charm quark (Nf 2 + 1 + 1). Recent results on fluctuations of conserved charges (ratios of generalized susceptibilites) are reviewed and an update on crosscheck calculations using other complementary lattice actions is given. For all our final results, the systematics are controlled, quark masses are set to their physical values, and the continuum limit is taken using at least three lattice spacings corresponding to temporal extents up to NT16.
