Thermal dileptons in a coarse-grained transport dynamics — •Maximilian Wiest1, Tetyana Galatyuk1,2, Ralf Rapp3, Florian Seck1, and Joachim Stroth2,41TU Darmstadt — 2GSI, Darmstadt — 3Texas A&M Univ, College Station, USA — 4Goethe-Universität, Frankfurt

Dileptons provide a unique way to access the properties of the fireball created in heavy-ion collisions. Hadrons are not suited for doing this in the same way, since their properties are subject to the strong interactions in the fireball. We study dilepton production in the SIS18 energy range by utilizing an approach that uses coarse-grained transport simulations to calculate thermal dilepton emission applying state-of-the-art in-medium spectral functions from hadronic many-body theory. To ensure an accurate description of the fireball, we have used several microscopic transport models and compared the effect of the space-time evolution on resulting dilepton spectra. We will also present a systematic comparison of the results for different colliding nuclei as well as for the number of individual participants in the collision (system size) and different collision energies as measured recently by the HADES Collaboration.
