Evidence for 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 wit...
