VALUE (MeV) DOCUMENT ID TECN  COMMENT $6087.2 \pm0.2 \pm0.5$ 1, 2 AAIJ 2023 AU LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV 1  Observed in ${{\mathit \Xi}_{{{b}}}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ channel with ${{\mathit \Xi}_{{{b}}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{{c}}}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit \Xi}_{{{b}}}^{0}}$ $\rightarrow$ ${{\mathit \Xi}_{{{c}}}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ and ${{\mathit \Xi}_{{{c}}}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}$. Measured as mass difference, listed separately. 2  AAIJ 2023AU measures $\mathit m({{\mathit \Xi}_{{{b}}}{(6087)}^{0}}$) $−$ $\mathit m({{\mathit \Xi}_{{{b}}}^{0}}$) $−$ 2$\mathit m({{\mathit \pi}^{\pm}}$) = $16.20$ $\pm0.20$ $\pm0.06~$MeV. We have adjusted the measurement to our best values of $\mathit m({{\mathit \Xi}_{{{b}}}^{0}}$) = $5791.9$ $\pm0.5$ (MeV), $\mathit m({{\mathit \pi}^{\pm}}$) = $139.57039$ $\pm0.00018$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
