QCD Phase Diagram in Nonlocal Chiral Quark Models

The QCD phase diagram is analyzed within chiral quark models with nonlocal separable interactions. For the case of two light flavors, we describe in detail the characteristics of the chiral phase transition in the T - μ plane, and analyze the color superconducting phase transition taking place at relatively large chemical potentials. We also consider the three-flavor version of the models, analyzing the predictions for masses and decay constants of light pseudoscalar mesons.
