| Abstract | The CERES/NA45 experiment at the CERN-SPS is dedicated to study the production of e sup + e sup - -pairs in ultrarelativistic heavy ion collisions. Compared to extrapolations from results obtained in proton-induced reactions, it has previously observed an enhanced production in S-Au and Pb-Au collisions. To verify this enhancement and to study its properties, higher statistics were accumulated during a runtime in 1996. We report here, for the first time, on the results of this analysis. |
