|Title:||Observation Of The Ξ0 → ∑+ μ-̄νμ Decay|
|Abstract:||The KTeV experiment at Fermilab provides a good opportunity to investigate the neutral cascade semi-leptonic decays. The Ξ0 muon semi-leptonic decay, Ξ0 → ∑+ μ-̄νμ, is suppressed by phase space with only 21 MeV of release energy, making it difficult to be investigated. The study of this decay has a theoretical motivation since it provides another instance to test the Standard Model of particle physics. In this analysis we have observed the Ξ0 → ∑+ μ- ̄νμ decay and measured its Branching Ratio using Ξ0 → Λπ0 decay as the normalization mode. © 2005 Elsevier B.V. All rights reserved.|
