1  Reconstructed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ , ${{\mathit \Omega}_{{c}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Reference ${{\mathit \Xi}_{{b}}^{-}}$ mass $5797.72$ $\pm0.6$ MeV from AAIJ 2014B.
2  Uses ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ and ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ decays, with the first evidence for ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Omega}_{{c}}^{0}}{{\mathit \pi}^{-}}$ at 3.3 $\sigma $ significance.
3  Measured in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ with $19$ $\pm5$ events.
4  Observed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ decays with $16$ ${}^{+6}_{-4}$ candidates, a significance of 5.5 sigma from a combined mass-lifetime fit.
5  Observed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ decays with $17.8$ $\pm4.9$ $\pm0.8$ candidates, a significance of 5.4 sigma.
