Search for the exotic ${\Xi }^{--}(1860)$ Resonance in 340GeV/c ${\Sigma }^{-}$-Nucleus Interactions

WA89 Collaboration

We report on a high statistics search for the ${\Xi }^{--}(1860)$ resonance in ${\Sigma }^{-}$-nucleus collisions at 340GeV/c. No evidence for this resonance is found in our data sample which con…
