Abstract

We measure the pressure and energy density of two flavor QCD in a wide range of quark masses and temperatures. The pressure is obtained from an integral over the average plaquette or ψ̄ψ. We measure the QCD β function, including the anomalous dimension of the quark mass, in new Monte Carlo simulations and from results in the literature. We use it to find the interaction measure, -3p, yielding nonperturbative values for both the energy density and the pressure p.
