QCD phase structure at finite temperature in three-flavor random matrix theory

The QCD phase structure is studied at finite temperature in a three-flavor random matrix model formulated with nonzero quark chemical potentials. In the case of no flavor mixing, we analytically obtain temperature dependent critical chemical potentials for finite quark masses. Numerical results show that the QCD phase diagram as a function of temperature is qualitatively in agreement with the prediction of the Nambu-Jona-Lasinio model.
