Abstract

We report on a measurement of the Ω0c lifetime using Ω0c → Ω− π þ decays reconstructed in eþ e− → cc̄ data collected by the Belle II experiment and corresponding to 207 fb−1 of integrated luminosity. The result, τðΩ0c Þ ¼ 243 48ðstatÞ 11ðsystÞ fs, agrees with recent measurements indicating that the Ω0c is not the shortest-lived weakly decaying charmed baryon.
