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.
