Low-Energy K$$^{-}$$ Nucleon/Multi-nucleon Interaction Studies by AMADEUS

The AMADEUS collaboration aims to provide new experimental constraints to the \(K^{-}\)N strong interaction in the regime of non-perturbative QCD, exploiting low-energy \(K^{-}\) hadronic interactions with light nuclei (e.g. H, \({}^{4}\)He, \({}^{9}\)Be and \({}^{12}\)C). The low-momentum kaons (\(p_{K}\) \(\sim \) 127 MeV/c) produced at the DA\(\Phi \)NE collider are ideal to explore both stopped and in-flight \(K^{-}\) nuclear captures. The KLOE detector is used as an active target, allowing to achieve excellent acceptance and resolutions for the data. In this work the results obtained from the study of \(\varLambda \pi ^{-}\) and \(\varLambda p\) correlated production in the final state are presented.
