The KLOE experiment has collected an integrated luminosity of about 2.5fb-1at the Ï factory DAÏNE. Ï radiative decays have been used to investigate the properties of the light scalar mesonswhose structure is still controversial. A direct search of Ï(600) â Ï0Ï0decay has been performed with data taken at 1 GeV, where Ïdecays are suppressed. The whole KLOE data set includes also 100 million η's produced through the radiative decay Ï â ηγ and tagged by means of the monochromatic recoil photon. From this sample we have investigated η decays relevant to test ChPT predictions. We present published and preliminary results achieved from full statistics. © 2010 American instituteof physics.

Abstract
The KLOE experiment has collected an integrated luminosity of about 2.5fb-1at the Ï factory DAÏNE. Ï radiative decays have been used to investigate the properties of the light scalar mesonswhose structure is still controversial. A direct search of Ï(600) â Ï0Ï0decay has been performed with data taken at 1 GeV, where Ïdecays are suppressed. The whole KLOE data set includes also 100 million η's produced through the radiative decay Ï â ηγ and tagged by means of the monochromatic recoil photon. From this sample we have investigated η decays relevant to test ChPT predictions. We present published and preliminary results achieved from full statistics. © 2010 American instituteof physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
