VALUE (MeV) DOCUMENT ID TECN  COMMENT $\bf{ 6152.5 \pm0.4}$ OUR AVERAGE $6152.7 \pm1.2 \pm0.2$ 1 SIRUNYAN 2020 K CMS ${{\mathit p}}{{\mathit p}}$ at 13 TeV $6152.51$ $\pm0.26$ $\pm0.27$ 2 AAIJ 2019 AJ LHCB ${{\mathit p}}{{\mathit p}}$ at 7, 8, 13 TeV 1  SIRUNYAN 2020K measures $\mathit m({{\mathit \Lambda}_{{b}}{(6152)}^{0}}$ ) $−$ $\mathit m({{\mathit \Lambda}_{{b}}^{0}}$ ) = $533.1$ $\pm1.1$ $\pm0.4$ 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. 2  Observed in ${{\mathit \Lambda}_{{b}}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ mode.
