Electromagnetic Radiation from Hot and Dense Hadronic Matter

Abstract

The modifications of hadronic masses and decay widths at finite temperature and baryon density are investigated using a phenomenological model of hadronic interactions in the Relativistic Hartree Approximation. We consider an exhaustive set of hadronic reactions and vector meson decays to estimate the photon emission from hot and dense hadronic matter. The reduction in the vector meson masses and decay widths is seen to cause an enhancement in the photon production. It is observed that the effect of ρ\rho-decay width on photon spectra is negligible. The effects on dilepton production from pion annihilation are also indicated.
