A feasibility study has been performed in order to investigate the performance of the HADES detector to measure the electromagnetic decays of the hyperon resonances Σ (1385) 0 , Λ (1405) and Λ (1520) as well as the production of double strange baryon systems Ξ - and Λ Λ in p + p reactions at a beam kinetic energy of 4.5 GeV . The existing HADES detector will be upgraded by a new Forward Detector, which extends the detector acceptance into a range of polar angles that plays a crucial role for these investigations. The analysis of each channel is preceded by a consideration of the production cross-sections. Afterwards the expected signal count rates using a target consisting of either liquid hydrogen or polyethylene are summarized. [ABSTRACT FROM AUTHOR]
