Abstract: -ray spectroscopy of light kaonic atoms is a unique tool to provide precise information on the fundamental K̄N interaction at the low-energy limit and the in-medium nuclear interaction of K−. The future experiments of kaonic deuterium strong-interaction shift and width (SIDDHARTA-2 and J-PARC E57) can extract the isospin dependent K−N interaction at threshold. The high-resolution X-ray spectroscopy of kaonic helium with microcalorimeters (J-PARC E62) has the possibility to solve the long-standing potential-strength problem of the attractive K−-nucleus interaction. Here, the recent experimental results and the future projects of X-ray spectroscopy of light kaonic atoms are presented. [ABSTRACT FROM AUTHOR]

Abstract: The SIDDHARTA collaboration measured kaonic ³He and 4He 3d → 2p X-rays with gaseous targets at the DAΦNE e+e- collider. The 2p-state strong-interaction shifts and widths were precisely determined by using 144 high-resolution silicon drift detectors. The shift of K-4 He is in good agreement with theoretical calculations and consistent with the recent experimental result of KEK-PS E570. The shift of K-3 He is also determined for the first time. The newly determined widths are in agreement with optical model calculations. [ABSTRACT FROM AUTHOR]

Abstract: Studies of the low-energy ...N interaction have been performed based on X-ray spectroscopy of light kaonic atoms by the SIDDHARTA experiment, where the K-series lines of kaonic hydrogen and deuterium, and the L-series lines of kaonic ³He and 4He were measured, as well as kaonic atom X-ray transitions produced in Kapton. This article deals with the short summary of the results of these measurements in the SIDDHARTA experiment. [ABSTRACT FROM AUTHOR]

Abstract: 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 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, 4He, 9Be and 12C 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.
