From a sample of about 109 φ-mesons produced at DAΦNE, we select KL and KS tagged mesons. We present the results on the search for KS → 3π 0, the first observation of KS → πμν, and the measure the major KL branching ratios, including the semileptonic decays relevant for the |V us| determination. A measurement of the KL lifetime, using KL→π 0 π 0 π 0 decays, is also given.

Abstract
From a sample of about 109 φ-mesons produced at DAΦNE, we select KL and KS tagged mesons. We present the results on the search for KS → 3π 0, the first observation of KS → πμν, and the measure the major KL branching ratios, including the semileptonic decays relevant for the |V us| determination. A measurement of the KL lifetime, using KL→π 0 π 0 π 0 decays, is also given.File in questo prodotto:
