چکیده
The KLOE experiment1 runs at the Frascati φ factory DAΦNE, a high luminosity e+e− collider working at √ s ∼ 1020 MeV, corresponding to the φ meson mass. The KLOE detector consists of a large cylindrical drift chamber 2, surrounded by a sampling lead-scintillating fiber electromagnetic calorimeter 3. Both detectors operate inside a uniform magnetic field of ∼ 0.5 T provided by a superconducting coil. In the whole data taking (2001− 2006) KLOE has collected an integrated luminosity of 2.5 fb−1 corresponding to about 8 billions of φ produced, plus some off-peak data (200 pb−1 at 1 GeV). The KLOE trigger system 4 is highly efficient on most of the φ decay.

KAON PHYSICS AT KLOE THE KLOE COLLABORATION a
The most precise determination of Vus comes from semileptonic kaon decays. We have measured with the KLOE detector at DAΦNE, the Frascati φ factory, all the experimental inputs to Vus for both neutral and charged kaons. Using our results we extract the value of Vus with ∼ 0.9% fractional error, which is entirely dominated by the theoretical error on the knowledge of the normalization of the dec...
متن کاملRecent results from KLOE
In this report I will present the recent results on K mesons from the KLOE experiment at the DAFNE ee collider working at the center of mass energy ∼ 1GeV ∼ mφ. They include Vus determinations, the test on the unitarity of the first row of the CKM matrix and the related experimental measurements. Tests of lepton universality from leptonic and semileptonic decays will be also discussed. Then I w...
متن کاملThe new analysis of the KLOE data on the φ → ηπ 0 γ decay
In this paper we present the fit to the recent high-statistical KLOE data on the φ → ηπ 0 γ decay. This decay mainly goes through the a 0 γ intermediate state. The obtained results differ from those of the previous fits: data prefer a high a 0 mass and a considerably large a 0 coupling to the K ¯ K.

The KLOE experiment at DAΦNE has collected ∼ 450 pb −1 of e + e − collisions at center of mass energy W ∼ 1.02 GeV. Preliminary results are presented for the most recent measurements: limit on the BR(KS → 3π 0), BR of the Ke3 decay of the KS and determination of the hadronic cross section.
