1  Reconstructed in ${{\mathit \Xi}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{0}}{{\mathit \pi}^{-}}$ , ${{\mathit \Xi}_{{c}}^{0}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$ decays. Uses m(${{\mathit \Xi}_{{b}}^{0}}$) $−$ m(${{\mathit \Lambda}_{{b}}^{0}}$) = $172.44$ $\pm0.39$ $\pm0.17$ MeV from AAIJ 2014Z.
2  Derived from measurements in ${{\mathit \Xi}_{{b}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{c}}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit \Xi}_{{b}}^{-}}$ $\rightarrow$ ${{\mathit J / \psi}}{{\mathit \Xi}^{-}}$ from AALTONEN 2009AP taking correlated systematic uncertainties into account.
