Phase diagram of neutral quark matter: Self-consistent treatment of quark masses
Abstract
We study the phase diagram of dense, locally neutral three-flavor quark matter within the framework of the Nambu Jona-Lasinio model. In the analysis, dynamically generated quark masses are taken into account self-consistently. The phase diagram in the plane of temperature and quark chemical potential is presented. The results for two qualitatively different regimes, intermediate and strong diquark coupling strength, are presented. It is shown that the role of gapless phases diminishes with increasing diquark coupling strength.
