From a sample of about 10^9 φ mesons produced at DAFNE, we have selected KL mesons tagged by observing KS →pi+pi- decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus |. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL lifetime has also been measured.

Abstract
From a sample of about 10^9 φ mesons produced at DAFNE, we have selected KL mesons tagged by observing KS →pi+pi- decays. We present results on the major KL branching ratios, including those of the semileptonic decays needed for the determination of |Vus |. These branching ratio measurements are fully inclusive with respect to final-state radiation. The KL lifetime has also been measured.| File | Dimensione | Formato | |
