The Hadronic Gas Chiral Phase Transition within Generalized Chiral Perturbation Theory

Abstract

We study the temperature evolution of the quark-antiquark condensate below the chiral phase transition. The hadronic gas is described using a virial expansion within Generalized Chiral Perturbation Theory. In such way, we can implement both the large or small chiral condensate scenarios and analyze the condensate dependence on the values of the lightest quark masses.
