TI - Latest Results on Kaon Physics at KLOE-2 J2 - Proc. of eeFACT2022, Frascati, Italy, 12-16 September 2022 CY - Frascati, Italy T2 - ICFA Advanced Beam Dynamics Workshop on High Luminosity Circular e+e- Colliders T3 - 65 LA - english AB - The most recent results obtained by the KLOE-2 collaboration with entangled neutral kaons produced at DAΦNE are briefly reviewed: (i) an improved search for decoherence and CPT violation effects in the process phi -> KSKL -> pi+pi- pi+pi-, constraining with the utmost precision several phenomenological models; (ii) the first direct test of the T and CPT symmetries in neutral kaon transitions between flavor and CP eigenstates, by studying the processes phi -> KSKL -> pi+pi- pi e nu, phi -> KSKL -> pi e nu 3pi0; (iii) a new measurement of the KS -> pi e nu branching fraction, that in combination with the previous KLOE result improves the total precision by almost a factor of two, and allows a new derivation of f+(0) Vus.
