Physics at KAON : Hadron Spectroscopy, Strangeness, Rare Decays Proceedings of the International Meeting, Bad Honnef, 7–9 June 1989

"Physics at KAON", an international meeting jointly organized by the KFA Jillich and TRI­ UMF, was held in the Physikzentrum Bad Honnef from June 7 through June 9, 1989. This was one of a series of meetings - the first one in Europe - in which plans for the medium energy physics laboratory KAON were presented and some aspects of the physics at this new facility were discussed. The meeting focussed mainly on the topics of hadron spectroscopy, J{ -meson scattering, strangeness in nuclei, and rare decays. Also presented were some of the research programs at SATURNE and COSY which may well lead to KAON physics in the future. These proceed­ ings include articles which summarize our current experimental and theoretical knowledge in the various areas, as well as papers which describe lines of research feasible with KAON. The large number of participants - limited, in fact, by the capacity of the Physikzentrum - clearly demonstrates the great interest of the European physics community in the research avenues which will be opened by the high-intensity hadron facilities.

Topics focus on hadron spectroscopy, K-meson scattering, strangeness in nuclei, and rare decays, from experimental and theoretical points of view. Researchers in nuclear and particle physics will find this a thorough overview of the lines of research to be followed by SATURNE, COSY, and KAON.
