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.
