On the $$\hbox {K}^{-}$$ 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 $$\hbox {K}^{-}$$ 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.
