Aspects of the Quantum Chromo Dynamics Phase Diagram

Abstract

I briefly review some aspects of the Quantum Chromo Dynamics phase diagram at non zero temperature and quark chemical potential. I then suggest new possible phases which can appear in strongly interacting theories at non zero chemical potential. Finally I describe the phase diagram as function of the number of flavors and colors at zero quark chemical potential and zero temperature.
