| Title |
Equation of state for two flavor QCD at Nt=6 |
| Date |
1997-06 |
| Description |
We calculate the two flavor equation of state for QCD on lattices with lattice spacing a=(6T)21 and find that cutoff effects are substantially reduced compared to an earlier study using a=(4T)21. However, it is likely that significant cutoff effects remain. We fit the lattice data to expected forms of the free energy density for a second order phase transition at zero-quark mass, which allows us to extrapolate the equation of state to mq50 and to extract the speed of sound. We find that the equation of state depends weakly on the quark mass for small quark mass. |
