Meson properties from a bag model compared to lattice theory and heavy ion experiments

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A bag at temperature (T) with pressureB(T)=B(0)[1−(T/T c )4] is shown to be consistent with recent lattice data on the π and the ρ mesons. The limiting temperature,T l , of the pion bag from the Bekenstein entropy bound is lower than that of other mesons. This agrees with the thermal distribution of π,K and the ρ in heavy ion collisions, which (unlike proton-nucleus or pp data) show a marked difference inT of pion and other mesons in the mid-rapidity region.
