Abstract
The Frascati eþe collider, DANE, operates at a center of mass energy of 1020MeV, the mass of the f-meson. Three detectors have been realized, KLOE, DEAR, and FINUDA. The first two are presently collecting data in the two DANE interaction regions (IR), while the third is being assembled in its pit inside the DANE hall and will take data in the IR occupied by DEAR. The KLOE experiment, which is designed to measure CP and CPT violation parameters in the KSKL system, has collected so far 300 pb 1. Measurements obtained using the year 2000 data sample will be presented, which are focussed on KS physics and f radiative decays. The DEAR experiment aims at studying the scattering lengths of the kaon-nucleon system, through a precise measurement of the Ka line shifts in kaonic hydrogen and kaonic deuterium. With 2001 and 2002 data-taking periods the DEAR collaboration has demonstrated the capability of creating and detecting exotic atoms using the kaon flux from DANE, by measuring the X-ray spectrum of kaonic nitrogen. The present status and perspectives of the DEAR experiment will be discussed. A brief report will be given at the end on the FINUDA physics program, aiming at the study of the -hypernuclei levels and lifetimes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
