Phase transition in quantum chromodynamics
Bochkarev A. I. , Shaposhnikov M. E.
Quantum-chromodynamics sum rules are constructed for describing the spectrum of hadronic matter at finite temperatures. Analysis of these sum rules in the p-meson channel indicates a first-order phase transition accompanied by the disappearance of confinement at a temperature Tc с^140 MeV. The dynamic mass of the emitted quarks is found for temperatures near Tc. A phase transition accompanied by a restoration of chiral symmetry cannot occur before deconfinement.
