Chiral Phase Transition in Linear Sigma Model with Nonextensive Statistical Mechanics

Figure 4

Phase diagram of the -linear sigma model in the plane for various values. The results are plotted for four different values of with the vicinity of the -dependent CEP and the low temperature part of the curves enlarged in the inset. For more details, the dashed line stands for crossover transition and the solid one the first-order transition. CEPs are shown as star points.
