Liberation of dynamical quarks at high temperature

Abstract

Confinement of dynamical fields can be attributed to the absence of corresponding asymptotic states. Thermodynamical properties of such system are more appropriately formulated in terms of collective excitations of these fields, if they appear as particles. This mechanism is investigated in the mean-field quark model of confinement and hadronization. In this model, deconfinement and restoration of chiral symmetry happen simultaneously at certain critical temperature.
