${{\boldsymbol \Omega}{(2470)}^{-}}$

A peak in the ${{\mathit \Omega}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mass spectrum with a signal significance claimed to be at least $5.5$ standard deviations. There is no reason to seriously doubt the existence of this state, but unless the evidence is overwhelming we usually wait for confirmation from a second experiment before elevating peaks to the Summary Table.
