Sažetak
We review recently published and preliminary results from the KLOE Collaboration on scalar and pseudoscalar mesons. We present the extraction of fundamental f0(980) and a0(980) parameters from the Mππ and Mηπ spectrum with the first U.L. evaluation on the φ → K0K¯0γ branching ratio. Concerning the pseudoscalar sector we present the results on η −η ′ mixing and η ′ gluonic content, with the most precise measurement of the η mass and the investigation of the η → πππ dynamics from the Dalitz plot analysis. The study of the cross section for the processes e +e − → π +π −π 0π 0/π0π 0γ allow us to measure the OZI G-parity violating strongly suppressed decay φ → ωπ0.
