Role of the conserved charges in the chiral symmetry restoration phase transition

The effect of conserved baryon, isospin, and strangeness charges on the behavior of phase transitions in dense matter is studied. Baryonic matter is described within the three-flavor Polyalcov-Nambu-Jona-Lasinio model and several charge fractions Y-Q are considered. The role of the vector interaction, which can be important to describe dense systems, is discussed. Special attention is given to the case with charge fraction Y-Q = 0.4, due to its importance in heavy-ion collisions and core-collapse supernova matter. It is shown that the possible formation of chiral-symmetric quark matter in the laboratory will be favored in asymmetric matter. Besides, the inclusion of the vector interaction reinforces the formation of quark matter at lower densities.
