Abstract

The AMADEUS experiment deals with the investigation of the low-energy kaon-nuclei hadronic interaction at the DAΦNE collider at LNF-INFN. This study is fundamental to solve longstanding questions concerning interactions of strange quarks in the non-perturbative QCD. AMADEUS step 0 consisted in the reanalysis of the 2004/2005 KLOE data, exploiting K⁻ absorptions in H, ⁴He, ⁹Be and ¹²C, leading to the first invariant mass spectroscopy study with very low momentum (100 MeV/c) in-flight K⁻ captures. In this paper, we present an overview of the analysis strategy, with particular emphasis on the results obtained in the analyses of the events with correlated Σ⁰ and p.
