The last uncertainty is due to the uncertainty in the ${{\mathit \Omega}^{-}}$ mass. Also reported is ${\mathit m}_{{{\mathit \Omega}_{{{c}}}^{0}}}–{\mathit m}_{{{\mathit \Omega}^{-}}}$ = $1022.83$ $\pm0.07$ $\pm0.27$ MeV. 2  CRONIN-HENNESSY 2001 sees $40.4$ $\pm9.0$ events in a sum over five channels. 3  FRABETTI 1994H claims a signal of $42.5$ $\pm8.8$ ${{\mathit \Sigma}^{+}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ events. The background is about 24 events. 4  FRABETTI 1993 claims a signal of $10.3$ $\pm3.9$ ${{\mathit \Omega}^{-}}{{\mathit \pi}^{+}}$ events above a background of $5.8$ events. 5  ALBRECHT 1992H claims a signal of $11.5$ $\pm4.3$ ${{\mathit \Xi}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{+}}$ events. The background is about 5 events.
