Description:
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 $$Sigma (1385)^{0}$$ 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 $$4.5,{mathrm{GeV}}$$ 4.5 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.
