EnglishAbstract
Recent results obtained by the AMADEUS Collaboration on the experimental investigation of the K− low-energy interaction with light nuclei are summarised. The step 0 of AMADEUS consists in the analysis of the data collected at the DAΦNE collider with the KLOE detector during the 2004/2005 data taking campaign. The low momentum K− particles (pK ∼ 127 MeV/c) are absorbed in the light nuclei contained in the detector setup (H, 4He,9Be and12C) and hyperon–pion/hyperon–nucleons, emitted in the final state, are reconstructed. From the study of Λπ− and Λp correlated production, important information on the KN¯ strong interaction in the non-perturbative QCD regime are extracted
