Abstract

The KLOE experiment has collected 2.5 fb(-1) at the peak of the phi resonance at the e(+)e(-) collider DA Phi NE in Frascati and KLOE-2 is expected to start data taking at the upgraded DA Phi NE phi-factory late 2010, with the aim to collect 25 fb(-1) at the phi peak and it is under discussion the collection of 5 fb(-1) between 1 and 2.5 GeV. KLOE data have been used to investigate the properties of the light scalar mesons f(0)(980), a(0)(980) and light pseudoscalar mesons eta, eta', using phi radiative decays. Gamma-gamma interactions allow to investigate also the f(0)(600)/sigma meson, observing the reaction e(+)e(-) into e(+)e(-)pi(0)pi(0); a direct search of the f(0)(600)/sigma into pi(0)pi(0) decay is performed with data taken at a center of mass of 1 GeV, where phi decays are suppressed. We present ongoing analysis and final results already published with the full KLOE statistics and the scientific program of KLOE-2 collaboration on hadron physics.
