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.
