VALUE (MeV) DOCUMENT ID TECN  COMMENT $6339.7 \pm0.3 \pm0.5$ 1 AAIJ 2020 T LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV 1  AAIJ 2020T measures $\mathit m({{\mathit \Omega}_{{b}}{(6340)}^{-}})−\mathit m({{\mathit \Xi}_{{b}}^{0}}$) = $547.81$ $\pm0.26$ $\pm0.05$ MeV. We have adjusted the measurement to our best values of $\mathit m({{\mathit \Xi}_{{b}}^{0}}$) = $5791.9$ $\pm0.5$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
