Gap equation for the chiral-symmetry-restoration transition

Abstract
The chiral-symmetry-restoration transition in quantum chromodynamics is studied in analogy to the theory of superconductivity. Particular attention is paid to the dynamical quark mass and to the quark condensate as a function of temperature. A critical temperature Tc in the range of 170250 MeV is obtained. The relevance to heavy-ion collisions is discussed.
