First close-to-threshold measurement of the analyzing power Ay in the reaction p(pol)p -> pp eta

Abstract

At the internal facility COSY-11 a first measurement of the reaction p(pol)p -> pp eta near the production threshold has been performed. Results for the analysing power will be presented and a comparison with one meson exchange models will be discussed.
