Hyperon production in the reactions pn(p)→ K0 Λ p(p) and pp→ K+ Λ p — •Martin Krapp, Wolfgang Eyrich, and Florian Hauenstein — Universität Erlangen-Nürnberg
The near threshold production of hyperons by using a liquid hydrogen target is one of the main topics studied at the time-of-flight spectrometer COSY-TOF. Up to now the reactions pp→ K+ Λ p, K0 Σ+ p and K+ Σ0 p have been investigated in detail and led to an essential information gain about the reaction mechanism. In order to achieve more complete information about hyperon production near threshold in nucleon-nucleon reactions, the investigation has been extended to pn reactions by using a liquid deuterium target. The current status of the analysis of the reaction channel pn(p)→ K0 Λ p(p) will be presented. This includes reconstruction techniques, preliminary results from real data as well as Monte Carlo simulation including Fermi motion. The achieved cross section is compared to theoretical predictions and related reaction channels.
