VALUE (MeV) DOCUMENT ID TECN  COMMENT $6072.3 \pm2.9 \pm0.2$ 1 AAIJ 2020 Q LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV 1  AAIJ 2020Q measures $\mathit m({{\mathit \Lambda}_{{b}}{(6070)}^{0}}$) $−$ $\mathit m({{\mathit \Lambda}_{{b}}^{0}}$) = $452.7$ $\pm2.9$ $\pm0.5$ MeV. We have adjusted the measurement to our best value of $\mathit m({{\mathit \Lambda}_{{b}}^{0}}$) = $5619.60$ $\pm0.17$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
