STABILITY OF VACUUM AND QCD PHASE TRANSITION IN DYSON-SCHWINGER EQUATION APPROACH OF QCD

摘要

We describe briefly the effects of the running coupling strength, the current quark mass, the temperature and density on the QCD phase structure and its transition in the framework of Dyson-Schwinger equation approach of QCD. With a simple model, we show that the chiral susceptibility can identify the stability of the vacuum and plays an important role in describing the QCD Phase transition.
