Description
The AMADEUS experiment deals with the investigation of the low-energy kaon-nuclei hadronic interaction at the DAΦNE collider at LNF-INFN, which is fundamental to solve longstanding questions in the non-perturbative strangeness QCD sector. AMADEUS step 0 consisted in the reanalysis of 2004/2005 KLOE data, exploiting $K^−$ absorptions in H, ${}^4$He, ${}^9$Be and ${}^{12}$C, leading to the first invariant mass spectroscopy study with very low momentum (100MeV) in-flight $K^−$ captures. With AMADEUS step 1 a dedicated pure Carbon target was implemented in the central region of the KLOE detector, providing a high statistic sample of pure at-rest $K^−$ nuclear interaction.
The results obtained in the analyses of the hyperon-pion correlated events, searching for the resonant shapes of Y$^*$ states, and the analyses of hyperon-proton, deuteron, and triton correlations, searching for possible $K^-$-multi nucleon bound states, will be presented.
