Feasibility studies of low mass di-electrons with the HADES and CBM experiments at FAIR SIS100 — •Marten Becker for the HADES collaboration — Justus-Liebig-Universität Giessen

The High Acceptance DiElectron Spectrometer (HADES) and the Compressed Baryonic Matter experiment (CBM) are dedicated to study strongly interacting matter at high net-baryon densities and moderate temperatures. di-electrons as penetrating probes are a key observable to get direct access to the properties of the fireball generated in A+A collisions.

Currently the HADES experiment is located at SIS 18 at GSI, Darmstadt and will be moved in future to continue its physics program at SIS100 where higher beam energies are available. Both experiments, HADES and CBM are complementary to each other in terms of detector setup and measureable energy range making it interesting to study one system at both experiments for comparison and verification of the CBM results. Currently Ag+Ag collisions at 4.5A GeV is favored.

We present di-electron feasibility studies based on simulated Ag+Ag collisions at 4.5A GeV for the HADES and CBM detector setup and compare the results.
