The CERES/NA45 experiment at the CERN-SPS is dedicated to study the production of e+e--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 [1] and Pb-Au [2] collisions
The mass distribution for excess dielectrons in S + Au collisions at 200 A GeV measured by the CERES collaboration at CERN Super Proton Synchrotron is analyzed. The data are seen to be in satisfactory agreement with a scenario where a thermalized quark-gtuon plasma is formed initially, which expands
