1  Measured 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 relative to ${{\mathit \Xi}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{0}}{{\mathit \pi}^{-}}$ , ${{\mathit \Xi}_{{c}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays with reference ${{\mathit \Xi}_{{b}}^{-}}$ mean life $1.599$ $\pm0.06$ ps from AAIJ 2014B.
2  Measured in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Omega}^{-}}$ decays.
3  Observed in ${{\mathit \Omega}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Omega}^{-}}$ decays with $16$ ${}^{+6}_{-4}$ candidates, a significance of 5.5 sigma from a combined mass-lifetime fit.
