Measurement of the Ω 0 c lifetime at Belle II

F. Abudinén et al. (Belle II Collaboration)

We report on a measurement of the Ω0 c lifetime using Ω0 c → Ω−πþ decays reconstructed in eþe− → cc¯ data collected by the Belle II experiment and corresponding to 207 fb−1 of integrated luminosity. The result, τðΩ0 cÞ ¼ 243 48ðstatÞ 11ðsystÞ fs, agrees with recent measurements indicating that the Ω0 c is not the shortest-lived weakly decaying charmed baryon.
