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: $μ_{B}=(μ_{u}+μ_{d})/2$, $μ_{I}=(μ_{u}-μ_{d})/2$. This study completes a previous analysis where only small isospin chemical potentials $μ_{I}$ were considered
