| Abstract | We report on a measurement of the \Omgc lifetime using $\Omgc\to\Omg\pip$ decays reconstructed in the \epem-collision data collected by Belle~II between 2019 and the first half of 2021, which correspond to \lumi of integrated luminosity. The result, $\tau(\Omgc)=\tauOmgc\pm\tauOmgcStat\pm\tauOmgcSyst\fs$, agrees with recent measurements indicating that the \Omgc is not the shortest-lived weakly decaying charm baryon. |
