    "abstract": "The modifications of hadronic masses and decay widths at finite temperature\nand baryon density are investigated using a phenomenological model of hadronic\ninteractions in the Relativistic Hartree Approximation. We consider an\nexhaustive set of hadronic reactions and vector meson decays to estimate the\nphoton emission from hot and dense hadronic matter. The reduction in the vector\nmeson masses and decay widths is seen to cause an enhancement in the photon\nproduction. It is observed that the effect of $\\rho$-decay width on photon\nspectra is negligible. The effects on dilepton production from pion\nannihilation are also indicated.",
