1  AAIJ 2020Q measures $\mathit m({{\mathit \Lambda}_{{{b}}}{(5912)}^{0}}$) $−$ $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $292.589$ $\pm0.029$ $\pm0.010$ MeV. We have adjusted the measurement to our best value of $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $5619.57$ $\pm0.16$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
2  SIRUNYAN 2020K measures $\mathit m({{\mathit \Lambda}_{{{b}}}{(5912)}^{0}}$) $−$ $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $292.72$ $\pm0.12$ $\pm0.01$ MeV. We have adjusted the measurement to our best value of $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $5619.57$ $\pm0.16$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
3  Observed in ${{\mathit \Lambda}_{{{b}}}{(5912)}^{0}}$ $\rightarrow$ ${{\mathit \Lambda}_{{{b}}}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays with $17.6$ $\pm4.8$ candidates with a significance of 5.2 sigma.
4  AAIJ 2012AL measures $\mathit m({{\mathit \Lambda}_{{{b}}}{(5912)}^{0}}$) $−$ $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $292.60$ $\pm0.12$ $\pm0.04$ MeV. We have adjusted the measurement to our best value of $\mathit m({{\mathit \Lambda}_{{{b}}}^{0}}$) = $5619.57$ $\pm0.16$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
