Towards reconstructing dilepton flow in Au+Au collisions at low energies with HADES^* — •Sukyung Kim for the HADES collaboration — Bergische Universität Wuppertal, Wuppertal, Germany

In March 2024, the High Acceptance DiElectron Spectrometer (HADES) at GSI Darmstadt, Germany will collect data on dielectron production in Au+Au collisions at beam energies ranging from 0.2 to 0.8 A GeV. One specific focus will be to characterize the collision system studying dielectron flow. In the HADES experiment, the Ring-Imaging CHerenkov (RICH) detector is responsible for efficient electron identification. Thus, the performance of the RICH will be the first crucial factor in dielectron flow extraction. In this contribution we will discuss the calibration and performance of the HADES RICH used for electron identification. Additionally, we will discuss preparatory simulation studies produced using the SMASH transport model.
