Flavor-Mixing Effects on the QCD Phase Diagram at non-vanishing Isospin Chemical Potential: One or Two Phase Transitions?

M. Frank, M. Buballa, M. Oertel

We investigate effects of a fixed nonzero isospin chemical potential on the mu_B-T phase diagram of strongly interacting matter using a Nambu--Jona-Lasinio-type four fermion intera…
