Dilepton production in heavy-ion collisions at SIS energies — •Janus Weil1,2 and Ulrich Mosel1 — 1Institut für Theoretische Physik, Justus-Liebig-Universität Giessen, Heinrich-Buff-Ring 16, D-35392 Giessen, Germany — 2Present address: Frankfurt Institute for Advanced Studies (FIAS), Ruth-Moufang-Str. 1, D-60438 Frankfurt
We investigate dilepton production at SIS energies in a transport approach. As a first step, we fix the elementary cocktail composition in vacuum via dilepton data from nucleon-nucleon and light nucleus-nucleus collisions, where particular attention is drawn to the contributions of baryonic resonances.
Furthermore, we investigate the density and system-size dependence of
dileptonic observables and discuss the influence of in-medium spectral
functions on dilepton spectra from heavy-ion collisions.
