Pion dispersion relation in hot pion matter

Abstract

The modification of the pion propagation properties is studied when it is embedded in hot pionic matter. The real part and the imaginary part of the pion self-energy is calculated in a scheme, analogous to the Brueckner-Hartree-Fock approximation used in nuclear physics, which allows to incorporate in a fully consistent way unitarity and Bose correlations at finite temperature. The consequences of the medium effects on the pion transverse momentum spectrum measured in ultrarelativistic heavy ion collisions and the so-called soft pion puzzle are discussed.
