QCD thermodynamics with Wilson quarks at large κ

We extend our study of the high temperature transition with two flavors of Wilson quarks on 12³×{}6 lattices to {κ}=0.19. We also perform spectrum calculations on 12³×{}24 lattices at {κ}=0.19 to find the physical lattice spacing and quark mass. At this value of {κ} the transition is remarkable in that the plaquette and {ψ}{}{ψ} 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 {ρ} mass as a standard, the result is about 150 MeV, in agreement with the value found for the thermal transition with Kogut-Susskind quarks.
