Dilepton Production in Elementary Nuclear Reactions — •Janus Weil and Ulrich Mosel — Institut für Theoretische Physik, Universität Giessen, Germany

We present dilepton spectra from elementary nuclear reactions, which have been calculated via a semi-classical BUU transport model. We treat photon-induced reactions, as measured by the g7 experiment at JLAB, as well as proton-induced reactions, which have been measured by the KEK-PS E325 and the HADES collaborations. Our analysis aims for an investigation of possible in-medium modifications of the light vector mesons and their influence on experimentally accessible dilepton spectra.
