Chiral symmetry and the pion gas virial expansion
A. Dobado, J. R. Pelaez
Abstract
In this work we study the thermodynamic properties of the pion gas starting from the realistic elastic scattering phase-shifts obtained from Chiral Perturbation Theory and using the virial expansion. In particular we study the state equation and the behavior of the quark condensate as a function of the temperature and the density.
