VALUE (MeV) DOCUMENT ID TECN  COMMENT $6226.8 +1.4 -1.5 \pm0.6$ 1, 2 AAIJ 2021 LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV 1  AAIJ 2021 measures $\mathit m({{\mathit \Xi}_{{b}}{(6227)}^{0}}$) $−$ $\mathit m({{\mathit \Xi}_{{b}}^{-}}$) = $429.8$ ${}^{+1.4}_{-1.5}$ $\pm0.3$ MeV. We have adjusted the measurement to our best value of $\mathit m({{\mathit \Xi}_{{b}}^{-}}$) = $5797.0$ $\pm0.6$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values. 2  Uses ${{\mathit \Xi}_{{b}}^{-}}{{\mathit \pi}^{+}}$ decays.
