On SU(3) Effective Models and Chiral Phase Transition

Figure 1

The thermal behaviour of the dimensionless chiral order parameter, , calculated as function of temperature from the four effective models, PLSM (solid curve), QLSM (dotted curve), PNJL (double-dotted curve), and HRG (dash-double-dotted curve), and compared with the lattice QCD calculations (solid circles) [47] and (open circles) [48] at .
