title = "Observation of the Decay Ξ0→Σ+e-νe ",
abstract = "We present the first observation of Ξ0 beta decay using the KTeV beam line and detector at Fermilab. We have identified 176 beta decay events after subtracting a 7 event background. Normalization to 41 024 simultaneously collected Ξ0→ Λ0π0 decays yields a branching ratio of Γ(Ξ0→Σ+ e-νe)/Γ total =(2.71 ± 0.22statistical ± 0.31 systematic) × 10-4. The flavor symmetric quark model calculation agrees with this result.",
