| Annotation | A dense and hot pion system with a dynamically fixed particle number and an arbitrary charge is investigated with respect to ultra-relativistic heavy-ion collisions. The Lagrangian for describing such a system is derived from Weinberg's chiral Lagrangian for the pion-pion interaction. Pion polarization operators are calculated within the Hartree approximation. The pion spectrum in the isospin symmetrical gas is presented. The effective inmedium pion gap depends sensitively on the density and the temperature, and it is found to exceed both the free pion mass and the corresponding value for the pion gas in chemical equilibrium. The possibility of a BoseEinstein condensation is also discussed |
