Observation of an Exotic S = -2, Q = -2 Baryon Resonance in Proton-Proton Collisions at the CERN SPS

Results of resonance searches in the $\Xi^{-} \pi^{-}, \Xi^{-} \pi^{+}, \bar{Xi}^{+} \pi-$ and $\bar{Xi}^{+} \pi^{+}$ invariant mass spectra in proton-proton collisions at $\sqrt{s}=17.2$ GeV are presented. Evidence is shown for the existence of a narrow $\Xi^{-} \pi^{-}$ baryon resonance with mass...
