Abstract
The KLOE experiment has collected an integrated luminosity of about 2.5 fb−1 at the φ factory DAφNE. φ radiative decays have been used to investigate the properties of the light scalar mesons f0(980)/a0(980), whose structure is still controversial.A direct search of σ(600)→π0π0 decay has been performed with data taken at 1 GeV, where φ decays are suppressed.The whole KLOE data set includes also 100 million η’s produced through the radiative decay φ→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.
