QCD thermodynamics with Wilson quarks at large

We extend our study of the high temperature transition with two flavors of Wilson quarks on 123×6 lattices to 0.19. We also perform spectrum calculations on 123×24 lattices at 0.19 to find the physical lattice spacing and quark mass. At this value of the transition is remarkable in that the plaquette and show a large discontinuity while the Polyakov loop changes very little. This and several other features of the transition are more suggestive of a bulk transition than a transition to a quark-gluon plasma. However, if the temperature is estimated using the mass as a standard, the result is about 150 MeV, in agreement with the value found for the thermal transition with Kogut-Susskind quarks.
