Results from KLOE at DA Phi NE

The KLOE experiment at the Frascati phi factory, DaPhine, has collected similar to500 pb(-1), i.e. 1.5 x 10(9) phi decays. At the phi factory it is possible to select pure K-L and K-S beams. Although the integrated luminosity is insufficient for precision tests of the CP, T symmetries in kaon decays, a wide number of topics in kaon and hadronic physics are accessible from the largest sample of (D decays at rest collected so far. The cross section sigma(e(+)e(-) --> pi(+)pi(-)gamma) below 1 GeV, relevant for the precise evaluation of the muon magnetic moment, has been measured with a statistical accuracy better than 1%. For the K-S, we obtained the ratio of the branching fractions Gamma(K-S --> pi(+)pi(-)(gamma))/Gamma(K-S --> pi(0)pi(0)) = (2.239 +/- 0.003(stat) +/- 0.015(syst)), fully inclusive of the pipigamma final state. The analysis of the similar to20,000 K-S semileptonic decays K-S --> piev is being finalized providing precise measurements of both, the K-S semileptonic branching ratio, and Re x(+), i.e. the DeltaS = DeltaQ rule violation parameter. For the K-L, we obtained the ratio Gamma(K-L --> gammagamma)/Gamma(K-L --> pi(0)pi(0)pi(0)) = (2.80 +/- 0.02(stat) +/- 0.02(syst)) x 10(-3), of interest to Chiral Perturbation Theory (ChPT), as well as preliminary results on the branching ratios to other decay modes. In particular, our measurements of the semileptonic decays of both, neutral, and charged kaons will improve the precision of the CKM matrix element V-us, clarifying the present disagreement between different experiments. The phi radiative decays, both in scalar and pseudo-scalar mesons, have been analyzed giving new measurements of the eta - eta' mixing angle, and of the phi --> a(0)(980)gamma, phi --> f(0)(980)gamma branching ratios
