On the K^- Absorptions in Light Nuclei by AMADEUS

The aim of the AMADEUS collaboration is to provide experimental information on the low-energy strong interaction of antikaons with nucleons, exploiting the absorptions of low momentum K^- mesons ( p_K∼ 127 MeV/c) produced at the DAΦNE collider, in the materials composing the KLOE detector setup, used as an active target. The K^- single and multi-nucleon absorptions in light nuclei ( ^4He and ^12C ) are investigated by reconstructing hyperon–pion, hyperon–nucleon/nucleus pairs, emitted in the final state of the reactions. In this paper the results obtained from the study of Λπ ^- , Λp and Λt correlated production are presented.
