KLOE results on scalar and pseudoscalar mesons
The data collected by the KLOE Collaboration at the Frascati φ-factory DAΦNE from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons no(980) and f0(980) into two pseudoscalar mesons have been exploited to measure the relevant parameters of those resonances. The radiative decays φ→ηγ and ηγ have been used for the determination of the pseudoscalar mixing angle and to search for a possible gluonium content in the η. The dynamics of the η→ 3π decay has been studied and the Dalitz Plot parameters have been measured. The large amount of η mesons produced allowed also to study interesting rare η decays.
