Hadron Physics results at KLOE-II experiment

Abstract

KLOE and KLOE-2 data (almost 8 fb −1 ) constitute the largest sample ever collected at an electronpositron 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 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.
