THE N-T=6 EQUATION OF STATE FOR 2 FLAVOR QCD

We improve the calculation of the equation of state for two flavor QCD by simulating on N-t = 6 lattices at appropriate values of the coupli ngs for the deconfinement/chiral symmetry restoration crossover. For a m(q) = 0.0125 the energy density rises rapidly to approximately 1 GeV/ fm(3) just after the crossover (m(pi)/m(rho) approximate to 0.4 at thi s point). Comparing with our previous result for N-t = 4 [1], we find large finite N-t corrections as expected from free field theory on fin ite lattices. We also provide formulae for extracting the speed of sou nd from the measured quantities.
