    "abstract": "Based on a realistic model for the rho meson in free space we investigate\nit\u0027s medium modifications in a hot hadron gas generated by hadronic\nrescattering processes, i.e. renormalization of intermediate two-pion states as\nwell as direct rho meson scattering off hadrons. Within the vector dominance\nmodel the resulting in-medium rho spectral function is applied to calculate\n$e^+e^-$ spectra as recently measured in heavy-ion collisions at CERN-SpS\nenergies in the CERES experiment.",
