,The Ξ hyperon,The Ξ hyperon is an isospin doublet (Ξ., Ξ.) with hypercharge . = -1. The cross sections for producing the Ξ in πN and . N collisions are much smaller than the corresponding cross sections for producing the Λ or ∑. For this reason, not as much is known about the Ξ as about these other two hyperons.
