VALUE (MeV) DOCUMENT ID TECN  COMMENT $\mathbf{5935.1}\pm \mathbf{0.5}$ OUR AVERAGE $5935.09\pm 0.01\pm 0.49$ 1, 2 AAIJ 2023 AU LHCB $\mathit{p}\mathit{p}$ at 7, 8, 13 TeV $5935.08\pm 0.02\pm 0.49$ 1, 3 AAIJ 2015 H LHCB $\mathit{p}\mathit{p}$ at 7, 8 TeV 1  Observed in ${\mathit{\Xi }}_b^0{\pi }^{-}$ channel with ${\mathit{\Xi }}_b^0$ $\to$ ${\mathit{\Xi }}_c^{+}{\pi }^{-}$ and ${\mathit{\Xi }}_c^{+}$ $\to$ $\mathit{p}{\mathit{K}}^{-}{\pi }^{+}$. 2  AAIJ 2023AU measures $\mathit{m}({\mathit{\Xi }}_b^{{}^{\prime }}{(5935)}^{-}$) $-$ $\mathit{m}({\mathit{\Xi }}_b^0$) $-$ $\mathit{m}({\pi }^{-}$) = $3.66$ $\pm 0.01$ $\pm 0.00$MeV. We have adjusted the measurement to our best values of $\mathit{m}({\mathit{\Xi }}_b^0$) = $5791.9$ $\pm 0.5$ (MeV), $\mathit{m}({\pi }^{-}$) = $139.57039$ $\pm 0.00018$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values. 3  AAIJ 2015H measures $\mathit{m}({\mathit{\Xi }}_b^{{}^{\prime }}{(5935)}^{-}$) $-$ $\mathit{m}({\mathit{\Xi }}_b^0$) $-$ $\mathit{m}({\pi }^{-}$) = $3.653$ $\pm 0.018$ $\pm 0.006$MeV. We have adjusted the measurement to our best values of $\mathit{m}({\mathit{\Xi }}_b^0$) = $5791.9$ $\pm 0.5$ (MeV), $\mathit{m}({\pi }^{-}$) = $139.57039$ $\pm 0.00018$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
