Resonance Regions: Partial Wave Analysis in the HADES Experiment — •Ahmed Marwan Foda — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt

The High Acceptance Di-lepton Spectrometer (HADES) collaboration uses a pion beam to study features of baryonic resonances and their decay channels. This allows the production of baryonic resonances at a fixed center of mass energy, i.e. in the s-channel, thus giving these beams a significant advantage relative to proton proton reactions. Partial Wave Analysis (PWA) techniques are used to study the coupling of the resonances to different final states. Analysis of the baryonic resonances decays to ρ N and ω N final states will provide insight into baryon-vector meson couplings essential for the understanding of the melting of the ρ N meson in a dense baryonic matter and description of dilepton emissions from Heavy Ion collisions.
A new implementation of the Bonn-Gatchina framework is being developed in preparation for a more detailed mapping of the resonance regions in pion-proton collisions. Example fits will be presented showing current status and the potential of the new framework.
