Phase diagram of dense QCD with and without neutrino trapping

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 diagrams in the plane of temperature and quark chemical potential, as well as in the plane of temperature and neutrino chemical potential are presented. We show that neutrino trapping favors two-flavor color superconductivity and disfavors color-flavor-locked phase at imtermediate densities of matter. The implications of these results for the evolution of protoneutron stars are briefly discussed.
