1  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.
2  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 $\mathit m({{\mathit \Lambda}_{{b}}^{0}}$) = $5619.60$ $\pm0.17$ (MeV). Our first error is their experiment's error and our second error is the systematic error from using our best values.
