Fitting the chiral phase transition data to fix the model parameters we establish another (deconfinement) phase transition which separates a new phase from hadronic matter. The parameters and properties of the phase diagram are discussed in comparison with lattice and other results.10 pages, LatexHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
