    "abstract": "Dilepton spectra are calculated within the microscopic transport model UrQMD\nand compared to data from the CERES experiment. The invariant mass spectra in\nthe region 300 MeV \u003c M \u003c 600 MeV depend strongly on the mass dependence of the\n$\\rho$ meson decay width which is not sufficiently determined by the Vector\nMeson Dominance model. A consistent explanation of both the recent Pb+Au data\nand the proton induced data can be given without additional medium effects.",
