Can extended duality uniquely explain the dilepton data in HICs at SPS?
B. Kampfer, K. Gallmeister, O. P. Pavlenko
Abstract
Extended duality is used to explain the dilepton data of heavy-ion experiments at CERN-SPS. Taking into account the background contributions (hadronic cocktail, Drell-Yan, semileptonic decays of open charm) the spectral shapes of the CERES, NA38/50 and HELIOS-3 data in experiments with lead and sulfur beams can be well described, however, the normalizations of the sulfur beam data are problematic.
