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

We study the phases of a two-flavor Nambu-Jona-Lasinio model at finite temperature T, and 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.
