Average hydrodynamic behaviour of a non-linear pion-pion chiral Lagrangian

  • Published:

Abstract

In the study of the behaviour of matter at superhigh densities (1016 g/cm3), the properties ofe +e− andp−p collisions are known to provide conditions which determine the equation of state. In this paper, assuming that a system of pions is a good representation ofp−p collisions, we study the hydrodynamic behaviour of an SU(2)×SU(2) chiral Lagrangian in theGasiorowicz-Geffen coordinates with symmetry-breaking terms included. This model possesses simple classical solutions. By the application of the averaging method ofMilekhin, we obtain the equation of state and discuss its implications.
