Measurement of the ${\mathrm{\Omega }}_c^0$ lifetime at Belle II

We report on a measurement of the ${\mathrm{\Omega }}_c^0$ lifetime using ${\mathrm{\Omega }}_c^0\to {\mathrm{\Omega }}^{-}{\pi }^{+}$ decays reconstructed in $e^{+}{e}^{-}\to c\bar{c}$ data collected by the Belle II experiment and corresponding to $207\mathrm{f}{\mathrm{b}}^{-1}$ of integrated luminosity. The result, $\tau ({\mathrm{\Omega }}_{\mathrm{c}}^0)=243\pm 48(\mathrm{s}\mathrm{t}\mathrm{a}\mathrm{t})\pm 11(\mathrm{s}\mathrm{y}\mathrm{s}\mathrm{t})\mathrm{f}\mathrm{s}$, agrees with recent measurements indicating that the ${\mathrm{\Omega }}_c^0$ is not the shortest-lived weakly decaying charmed baryon.
