Abstract

We analyse the QCD chiral phase transition in the nonlinear and linear σ-model. The strategy is the same in both cases. We fix the parameters of the effective meson theory at temperature T=0 and extrapolate the models to temperatures in the vicinity of the phase transition. The linear σ-model in SU(3)× SU(3) gives a crossover around T_c≈190 MeV. Around this temperature chiral SU(2)× SU(2) is almost restored. We also calculate meson masses as a function of temperature.
