Production and electromagnetic decay of hyperons: a feasibility study with HADES as a phase-0 experiment at FAIR

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 reac...

Beschreibung
Zusammenfassung:	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.
