Physics At Kaon

"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.

In 1947, the first of what have come to be known as "strange particles" were detected. As the number and variety of these particles proliferated, physicists began to try to make sense of them. Some seemed to have masses about 900 times that of the electron, and existed in both charged and neutral varieties. These particles are now called kaons (or K mesons), and they have become the subject of some of the most exciting research in particle physics. Kaon Physics at the Turn of the Millennium presents cutting-edge papers by leading theorists and experimentalists that synthesize the current state of the field and suggest promising new directions for the future study of kaons. Topics covered include the history of kaon physics, direct CP violation in kaon decays, time reversal violation, CPT studies, theoretical aspects of kaon physics, rare kaon decays, hyperon physics, charm: CP violation and mixing, the physics of B mesons, and future opportunities for kaon physics in the twenty-first century.

The neutral K meson or neutral kaon, K0, and its antiparticle, K(bar)0, form a remarkable quantum-mechanical two-state system that has played an important role in the history of elementary particle physics. Indeed, ever since the discovery of K0 half a century ago, neutral kaons have been a rich source of unique and facinating phenomena associated with their production, decay and propagation in both vacuum and matter. This overview conveys the unique beauty of a quantum-mechanical system that contains so many of the aspects of modern physics. WICHTIGE INFO: Satzanweisung!!! bitte setzen Sie bei K0 das Zeichen "0" als hochgestellte Null. K(bar) ersetzen Sie bitte, indem Sie über das K einen Querstrich setzen und das "(bar)" dann bitte löschen. Danke, jlenz(Tel. 307)

The author gives an overview of current plans for kaon physics at BNL. The program is centered around the rare decay modes K →?+?{bar?} and K{sub L} →?°{nu}{bar {nu}}.
