Phase diagrams of the three-flavor NJL model with color superconductivity and pseudoscalar condensation

Abstract

We present results of the calculation of phase diagrams of the three-flavor NJL model as a function of temperature and different quark chemical potentials. These phase diagrams are an extension of earlier calculations in the literature in which either only the possibility of color superconductivity or the possibility of pseudoscalar condensation was investigated. This study takes into account both options and hence allows one to investigate their competition. It turns out that the color superconducting phase and the phase in which the pseudoscalar mesons condense are separated by a first order transition.
