Non-equilibrium dilepton production in hadronic transport approaches — •Jan Staudenmaier1,2, Janus Weil2, and Hannah Petersen1,2,3 — 1Goethe Universität Frankfurt — 2Frankfurt Institute for Advanced Studies — 3GSI Helmholtzzentrum für Schwerionenforschung
In this talk the non-equilibrium dilepton production from a hadronic transport approach (SMASH) is presented. The dilepton emission from the hadronic stage is of interest for current HADES results measured at GSI in the beam energy range from 1.25 - 3.5 GeV. Also at high collision energies (RHIC/LHC) the later dilute stages of the reaction are dominated by hadronic dynamics.
First, the employed hadronic transport approach called SMASH (=Simulating Many Accelerated Strongly-interacting Hadrons) is introduced. The main contribution to the dilepton spectra in the low energy regime of GSI/FAIR/RHIC-BES originates from resonance decays. Treatment and results of the dilepton production with SMASH are shown, together with a comparison to HADES data.
Furthermore, the possibility of employing the non-equilibrium dilepton production from a hadronic transport approach combined with a hydrodynamic approach (hybrid model) to describe spectra for high collision energies (RHIC/LHC) is explored.
