Dilepton and photon emission rates from a hadronic gas. III

We extend our early analyses of the dilepton and photon emission rates from a hadronic gas to account for strange mesons using a density expansion. The emission rates are reduced to vacuum correlation functions using three-flavor chiral reduction formulas, and the latter are assessed in terms of empirical data. Using a fire- ball, we compare our results to the low and intermediate mass dilepton data available from CERN. Our results suggest that a baryon free hadronic gas does not account for the excess of low mass dielectrons observed at CERES but does well in accounting for the intermediate dimuons at HELIOS. The same observations apply to the recent low and high [Formula Presented] dielectron rates from CERES.
