1  Measured in ${{\mathit \Xi}_{{{c}}}^{0}}$ produced promptly in ${{\mathit p}}{{\mathit p}}$ collisions, using ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ as normalisation mode. AAIJ 2022Y reports this lifetime value as ($148.0$ $\pm2.3$ $\pm2.2$ $\pm0.2$) $ \times 10^{-15}$ s where the last uncertainty is due to the uncertainty on the ${{\mathit D}^{0}}$ lifetime value from PDG 2020 average, ${\mathit \tau}_{{{\mathit D}^{0}}}$ = ($410.1$ $\pm1.5$) fs.
2  AAIJ 2019AG reports [${{\mathit \Xi}_{{{c}}}^{0}}$ MEAN LIFE] $/$ [${{\mathit D}^{\pm}}$ MEAN LIFE] = $0.1485$ $\pm0.0017$ $\pm0.0016$ which we multiply by our best value ${{\mathit D}^{\pm}}$ MEAN LIFE = ($1.033$ $\pm0.005$) $ \times 10^{-12}$ s. Our first error is their experiment's error and our second error is the systematic error from using our best value.
3  Measured in ${{\mathit \Xi}_{{{c}}}^{0}}$ produced in semileptonic ${{\mathit \Xi}_{{{b}}}^{-}}$ decays.
