AbstractA feasibility study has been performed in order to investigate the performance of the HADES detector to measure the electromagnetic decays of the hyperon resonances$$\Sigma (1385)^{0}$$Σ(1385)0, $$\Lambda (1405)$$Λ(1405) and$$\Lambda (1520)$$Λ(1520) as well as the production of double strange baryon systems$$\Xi ^{-}$$Ξ- and $$\Lambda $$Λ$$\Lambda $$Λ in p + p reactions at a beam kinetic energy of$$4.5\,{\mathrm{GeV}}$$4.5GeV. 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.
