Pseudodeconfinement and dynamical confinement in the quark plasma.

Abstract

We elaborate upon phenomenological models of high-temperature hadronic matter at zero baryon density. We discuss the choice of a practical set of ``fundamental'' degrees of freedom, indicate their relationship to dynamically confined plasma modes, and suggest in what way they may account for the phase transition and other thermodynamic features. We offer a partial resolution to the conflict between the requirement of dynamical confinement and the apparent thermodynamic deconfinement of the plasma. When all quark masses are large, the quarks may appear to be deconfined, even though they are technically confined.
