Beschreibung
Summary: The Nambu-Jona-Lasinio model phase diagram for a 2 + 1 flavor quark system will be described using the temperature and chemical potential as thermodynamic properties. Various susceptibilities will be used in order to obtain several qualitatively different phase diagrams, and each will be analyzed in both the light and strange quark sectors. A crossover region will be defined for the light quarks and another for the heavier strange quark. We observe that, because of the 't Hooft flavor mixing interaction term, the strange quark transition is heavily influenced by the chiral restoration of the light sector and, as a consequence, two different crossover regions can be observed when constructing the phase diagram for the strange quark.
