Recent results from the KLOE experiment at DAΦNE

The KLOE experiment at DAΦNE has collected data for an integrated luminosity of ~ 1.3 fb-1 from e+e- collisions at center-of-mass energy around the ϕ-meson peak, W ~1.02 GeV . A selection of results obtained from a sample of 450 pb-1 of data acquired during year 2001 and 2002 is presented. Studying tagged KS and KL-mesons produced in the reaction e+e-→ϕ→KS KL we measured the branching ratio of the decay KS→πeν, the upper limit on the decay KS→π0π0π0, and the main KL decay branching ratios. Exploiting the initial state radiation in the reaction e+e-→π+π-γ, we extracted the hadronic cross-section as a function of the squared center-of-mass energy sπ of the π π system, in the range 0.35 < sπ < 0.95 GeV 2.
