Energy dependence of the Λ/Σproduction cross-section ratio in p-p interactions
Abstract.The production of the Λ- and Σ0-hyperons has been measured via the pp → pK+Λ/Σ0 reaction at the internal COSY-11 facility in the excess energy range between 14 and 60 MeV. The transition of… Expand
First close-to-threshold measurement of the analysing power Ay in the reaction p⃗p → ppη
At the internal facility COSY-11 a first measurement of the reaction \(\vec p\) p → ppη near the production threshold has been performed. Results for the analysing power will be presented and a… Expand
