    "abstract": "Dilepton production in proton- and nucleus-induced reactions is studied in\nrelativistic transport model using initial conditions determined by the string\ndynamics from RQMD. It is found that both the CERES and HELIOS-3 data for\ndilepton spectra in proton-nucleus reactions can be well described by the\n`conventional\u0027 mechanism of Dalitz decay and direct vector meson decay.\nHowever, to provide a quantitative explanation of the observed dilepton spectra\nin central S+Au and S+W collisions requires contributions other than these\ndirect decays. Introducing a decrease of vector meson masses in hot and dense\nmedium, we find that these heavy-ion data can also be satisfactorily explained.\nThis agrees with our earlier conclusions based on a fire cylinder model. We\nalso give predictions for Pb+Au collisions at 160 GeV/nucleon using current\nCERES mass resolution and acceptance.",
