Flavour Physics and CP Violation at KLOE-2

Parallel session talk Flavour Physics and CP Violation T08: Flavour Physics and CP Violation


Aleksander Gajos (Jagiellonian University)


KLOE-2 experiment at the upgraded e+e- DAΦNE collider of the INFN Laboratori Nazionali di Frascati collected about 5 fb$^{-1}$ at the center of mass energy of the $\phi$-meson. Together with the data set of its predecessor (KLOE) the total acquired data sample of 8 fb$^{-1}$ corresponds to 2.4$\times$10$^{10}$ $\phi$-meson produced, which is the largest sample ever collected at the $\phi$(1020) at e$^+$e$^−$ colliders.

The KLOE-2 Collaboration continues the KLOE long-standing tradition of flavour physics precision measurements in the kaon sector and search for Physics Beyond the Standard Model.

In this talk the latest results on $K_S$ rare decays are presented and discussed in the framework of Flavour Physics and CP Violation tests, among these the measurement of $K_S$ semileptonic branching ratios, using 1.7 fb$^{-1}$ KLOE data, and the search for the pure CP-violating $K_S\to3\pi^0$ decay with the KLOE-2 data set.
