Description

KLOE-2 extends the physics program of the forerunner KLOE experiment, especially in the field of discrete symmetries tests with neutral kaons. KLOE and KLOE-2 have collected together the largest sample of electron-positron collisions at an energy equal to the φ-meson mass, corresponding to about $2.4×10^{10}$ produced φ mesons. In this talk I will review the latest results on neutral kaon physics at KLOE together with the status and prospects of the analyses of KLOE-2 data. I will report about a new measurement of the charge asymmetry in $K_S$ semileptonic decays with 1.7 fb$^{-1}$ of KLOE data, which improves the sensitivity of previous measurements of about a factor two. Furthermore, I will discuss the status of the analysis devoted to directly test T and CPT symmetries in neutral kaons transitions, as well as the search of the pure CP-violating $K_S → 3\pi^0$ decay using part of the recently acquired KLOE-2 dataset.
