Description
Lattice calculations of the QCD equation of state have been improved considerably over recent years. Improved lattice discretization schemes drastically reduce the cut-off dependence inherent in the lattice approach and allow for reliable extrapolations to the
continuum limit.
We will discuss the current status of numerical calculations of the QCD equation of state. In particular we will present new results on the flavour and quark mass dependence of the energy density and pressure and discuss the contribution of strange quarks to bulk
thermodynamic observables.
