Abstract

Employing an extended three flavor version of the Nambu–Jona-Lasinio model, we discuss in detail the phase diagram of quark matter. The presence of quark as well as of diquark condensates gives rise to a rich structure of the phase diagram. We study in detail the chiral phase transition and the color superconductivity as well as color flavor locking as a function of the temperature and chemical potentials of the system.
