Chiral symmetry and the pion gas virial expansion

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 equation of state and the behavior of the quark condensate as a function...

Description
Summary: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 equation of state and the behavior of the quark condensate as a function of the temperature and the density. [S0556-2821(99)07801-7]
