Recent results on hadron physics at KLOE-2

Abstract

The KLOE-2 experiment at the Frascati φ−factory ended its data-taking in March 2018 collecting more than 5 fb−1 at the φ peak. The new data sample, together with the KLOE one, corresponds to 2.4 ×1010 φ and 3.1×108 η meson events. It represents the largest sample ever collected at the φ peak in e+e− colliders, allowing to study light mesons with unprecedented statistics. Recent results obtained with KLOE data on hadron physics e.g. – measurement of the running of the fine structure constant below 1 GeV, the combination of hadron cross section measurements with determination of $ a_\mu ^{\pi \pi } $, the new preliminary η → π+π− limit, and progress in γγ studies – will be presented.
