QCD THERMODYNAMICS WITH WILSON QUARKS AT LARGE-KAPPA

We extend our study of the high temperature transition with two flavor s of Wilson quarks on 12(3) x 6 lattices to kappa = 0.19. We also perf orm spectrum calculations on 12(3) x 24 lattices at kappa = 0.19 to fi nd the physical lattice spacing and quark mass. At this value of kappa the transition is remarkable in that the plaquette and ($) over bar p si psi show a large discontinuity while the Polyakov loop changes very little. This and several other features of the transition are more su ggestive of a bulk transition than a transition to a quark-gluon plasm a. However, if the temperature is estimated using the rho mass as a st andard, the result is about 150 MeV, in agreement with the value found for the thermal transition with Kogut-Susskind quarks.
