We present p+p data, measured by the HADES spectrometer at EKin(proton)=3.5 GeV. We have analyzed the final state p+ p→ pLK+ in view of a possible intermediate state p+ p→KNN + K+. The KNN is the lightest candidate for a cluster of an anti-kaon bound to nucleons, and a current topic of theoretical and experimental interest. We have analyzed our data with a Partial- Wave Analysis that includes also the production of intermediate N∗-resonances (→ K+Λ). The result of the fit describes the data well and a statistical test showed no major deviations between model and data which could be attributed to a production of a kaonic nuclear bound state. We have, thus, started to focus on the determination of an upper limit of its production cross section. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence. 27-31-January-2014 Sponsors: Conference code: 121992
