${{\mathit \Omega}{(2012)}^{-}}$

$I(J^P)$ = $0(?^{-})$ 
Seen in ${{\mathit \Xi}^{0}}{{\mathit K}^{-}}$ and ${{\mathit \Xi}^{-}}{{\mathit K}_S^0}$ decays with a combined significance of 8.3 standard deviations. BELLE results from JIA 2019 and JIA 2025 are incompatible. JIA 2025 claims the older analysis was based on an inaccurate model for decays.
