Title: Chiral phase transition in effective models
Abstract: Incorporating its most relevant global symmetry, chiral effective models are aimed at investigating, in a simplified framework, important aspects of the yet unsolved QCD.We review some recent results obtained in these models on the restoration of chiral and axial symmetries, on the boundary of the first order phase transition region in the m π ¡ m K -plane at vanishing baryonic chemical potential µ B , and on the µ B ¡ T phase diagram.
