$∣ V_{u s} ∣$ and $K_{S}$ Decays from Kloe

arXiv:hep-ex/0505089

Abstract

Recent results obtained by the KLOE experiment operating at DA $Φ$ NE, the Frascati $ϕ$ -factory, are presented. They mainly concern neutral kaon decays including the $K_{L}$ dominant branching ratios, the $K_{L}$ lifetime and the extraction of the $C K M$ parameter $V_{u s}$ from the $K_{L}$ semileptonic decays and lifetime. The best world upper limit on $K_S \to \pppo$ channel is also presented
