Description
The KLOE-2 experiment at the upgraded e+e- DAPHNE collider of the INFN Laboratori Nazionali di Frascati completed its data taking campaign at the end of Mach 2018, collecting more than 5 fb$^{-1}$ at the center of mass energy of the phi-meson. Together with the data set of its predecessor KLOE, the acquired data sample of 8 fb$^{-1}$ corresponds to 2.4$\times$10$^{10}$ $\phi$-meson produced: the largest sample ever collected at the $\phi$(1020) at e$^+$e$^−$ colliders.
KLOE-2 Collaboration activities are now focused on data reconstruction and analysis, continuing the KLOE long-standing tradition of flavour physics precision measurements in the kaon sector, to probe CKM unitarity and lepton universality, and search for Physics Beyond the Standard Model. Latest results on K$_S$ rare decays will be presented and discussed in the framework of Flavour Physics and CP Violation tests, among these the measurement of Ks semileptonic branching ratios, using 1.7 fb$^{-1}$ KLOE data, and the search for the pure CP-violating $K_S\to 3\pi^0$ decay with the newly acquired KLOE-2 data set.
