Abstract
The data collected by the KLOE Collaboration at the Frascati phi-factory DA Phi NE from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a(0)(980) and f(0)(980) into two pseudoscalar mesons have been exploited to measure the relevant parameters of those resonances. The radiative decays phi ->eta gamma and eta'gamma have been used for the determination of the pseudoscalar mixing angle and to search for a possible gluonium content in the eta'.The dynamics of the eta -> 3 pi decay has been studied and the Dalitz Plot parameters have been measured. The large amount of eta mesons produced allowed also to study interesting rare eta decays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
