Toward cold and dense antikaonic nuclear clusters

摘要

Experimental search for cold and dense anti-kaonic nuclear cluster systems has been tried since 1998. Recently, an important indication for the most basic cluster K − pp has been obtained from old data of DISTO on p + p →K + + p + Λ through Λ(1405) production as a doorway. This success now triggers an extended search for a double kaonic cluster K − K − pp. Ultimately we have possibility to investigate multi-kaonic objects and kaonic strangelets in heavy-ion reactions. In this paper I trace my personal reminiscences of collaborative work with Paul Kienle during which I enjoyed the same feeling and excitement as Paul for more than a decade.
