Abstract

The Ξ0 muon semileptonic decay has been observed for the first time with nine identified events using the KTeV beam line and detector at Fermilab. The decay is normalized to the Ξ0 beta decay mode and yields a value for the ratio of decay rates Γ(Ξ0→Σ+μ-ν̄μ)/ Γ(Ξ0→Σ+e-ν̄e) of [1.8-0.5+0.7(stat)±0.2(syst) ]×10-2. This is in agreement with the SU(3) flavor symmetric quark model.
