Abstract
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 \(\hbox {K}^{-}\) mesons (\(p_\mathrm {K} \sim \) 127 MeV/c) produced at the \(\hbox {DA}\mathrm {\Phi }\hbox {NE}\) collider, in the materials composing the KLOE detector setup, used as an active target. The \(\hbox {K}^{-}\) single and multi-nucleon absorptions in light nuclei (\(^4\hbox {He}\) and \(^{12}\hbox {C}\)) 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 \(\mathrm {\Lambda }\pi ^{-}\), \(\mathrm {\Lambda }\hbox {p}\) and \(\mathrm {\Lambda }\hbox {t}\) correlated production are presented.
