Abstract
We improve the calculation of the equation of state for two flavor QCD by simulating on Nt = 6 lattices at appropriate values of the couplings for the deconfinement/chiral symmetry restoration crossover. For amq = 0.0125 the energy density rises rapidly to approximately 1 GeV/fm3 just after the crossover (mπ/mρ ≈ 0.4 at this point). Comparing with our previous result for Nt = 4 [1], we find large finite Nt corrections as expected from free field theory on finite lattices. We also provide formulae for extracting the speed of sound from the measured quantities.
