The KLOE experiment at the Frascati ϕ-factory collected large samples of light mesons, providing precise knowledge of their decay dynamics. The η → π+π−γ decay has been studied to search for a possible contribution from chiral anomaly, while a new preliminary high statistics Dalitz plot analysis of the η → π+π−π0 will increase the accuracy of the light quark mass ratio. Pseudoscalar production associated to internal conversion of the photon into a lepton pair allows the measurement of the form factor Fp(q12 = Mϕ2, q22 > 0) in the kinematical region of interest for the VMD model. Detailed study of such decays has been performed both for ϕ → ηe+e− and ϕ → π0e+e− processes. Moreover, data collected at √s have been used to study hadron production in γγ interactions, providing the most precise measurement of the Γ(η → γγ) partial width.
