Abstract
The hyperon production in elementary proton induced reactions is studied ex clusively at the external COSY beam using the time-of-flight spectrometer T OF. For the associated strangeness production process pp --> K (+)Ap total and differential cross sections as well as Dalitz plots, mass spectra of th e subsystems and the A -polarization are measured. The data show evidence f or the influence of N* resonances and the p A -final state interaction on t he production process. In the actual step the production of Sigma (+) and S igma (0) hyperons in the channels pp --> K (0) Sigma (+) p, K (+) Sigma (+) n and K (+) Sigma (0) p is included. In the future in addition a polarized beam and a polarized target as well as a deuterium target will be used.
