Abstract

The AMADEUS experiment aims to provide unique quality data for K - interaction with nucleons and light nuclei, both at-rest and in-flight (for K - momenta of about 100 MeV). The goal is to solve longstanding open issues in the non-perturbative QCD in the strangeness sector, like the nature of the Lambda(1405) state, the resonant versus non-resonant yield in nuclear K - capture and the properties of kaonic nuclear clusters which are strongly related to the multi-nucleon absorption processes. We can take advantage of the DA PhiNE collider representing a unique source of monochromatic low-momentum kaons, whose nuclear interaction with the materials of the KLOE detector (used as an active target) furnish us excellent acceptance and resolution data for K - capture on H, 4He, 9Be and 12C, both at-rest and in-flight. AMADEUS step 0 consisted in the analysis of the 2004-2005 KLOE data. A second step consisted in the implementation in the central region of the KLOE detector of a pure graphite target, providing a high statistic sample of K - 12 C nuclear captures at rest. For the future, new setups for various dedicated targets are under preparation.
