In order to deepen our knowledge about the low energy dynamics of the ppKK system we investigated population of events for the pp-->ppK+K- reaction as a function of the invariant masses of two particle subsystems. Based for the first time on the low-energy K+K- invariant mass distributions and the generalized Dalitz plot analysis, we estimated the scattering length for the K+K- interaction.", "revisions": [ { "version": "v2", "updated": "2010-03-24T10:48:01.000Z" } ], "analyses": { "subjects": [ "25.40.Ep", "13.75.Jz", "13.75.Lb", "14.40.Aq" ], "keywords": [ "final state interaction", "generalized dalitz plot analysis", "cooler synchrotron cosy", "invariant mass distributions", "low energy dynamics" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 849707, "adsabs": "2010arXiv1003.4504S" } } }
