Abstract

The AMADEUS experiment deals with the investigation of the low-energy kaon-nuclei hadronic interaction at the DA Phi NE collider at LNF-INFN, which is fundamental to solve longstanding open questions in the non-perturbative strangeness QCD sector. AMADEUS step 0 consisted in the analysis of 2004-2005 KLOE data, exploring the K- absorptions in H, He-4, Be-9 and C-12 in-flight and at-rest. 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. For the future, a dedicated setup to perform detailed studies is under preparation. Our present analysis deals with the major open questions in hadron nuclear physics in the strangeness sector, namely how hadron masses and interactions change in nuclear environment, with a search ranging from kaonic nuclear clusters to strange baryon resonances and in-medium modification of the resonance parameters.
