A calculation of the QCD phase diagram at finite temperature, and baryon and isospin chemical potentials

Abstract

We study the phases of a two-flavor Nambu-Jona-Lasinio model at finite temperature $T$, baryon and isospin chemical potentials: ${\mu }_B=({\mu }_u+{\mu }_d)/2$, ${\mu }_I=({\mu }_u-{\mu }_d)/2$. This study completes a previous analysis where only small isospin chemical potentials ${\mu }_I$ were considered
