KLOE and KLOE-2 data (almost 8 fb−1) constitute the largest sample ever collected at an electron-
positron collider operating at the 𝜙 peak resonance. In total it corresponds to the production of
about 24 billion of 𝜙 mesons whose decays include about 8 billion pairs of neutral K mesons and
about 300 million 𝜂 mesons. A wide hadron physics program, investigating rare meson decays,
𝛾 − 𝛾 interaction, dark forces and hadronic cross section, is thus carried out by the KLOE-2
Collaboration. The latest results and present analysis of the KLOE-2 collaboration are presented.
