Systematics of pi0 and eta Dalitz decays in the Gold on Gold beam time of HADES

Lepton pairs emerging from decays of virtual photons are the most promising probes of dense hadronic matter. HADES measured systematically electron pair production in light, medium and heavy mass systems as well as in p and d induced reactions. The understanding of the corresponding experimental results calls for supporting studies from transport calculation. This contribution focuses on systematic studies of pi0 and eta Dalitz decays, relevant for the interpretation of the dynamics of the fireball created in the hot and dense stage. We compare a clean sample of simulated mesons created with the PLUTO event generator to UrQMD cocktail simulations as well as real measured lepton pair distributions.
