Abstract

We report on a measurement of the ωc0 lifetime using ωc0→ω-π+ decays reconstructed in e+e-→cc¯ data collected by the Belle II experiment and corresponding to 207 fb-1 of integrated luminosity. The result, τ(ωc0)=243±48(stat)±11(syst) fs, agrees with recent measurements indicating that the ωc0 is not the shortest-lived weakly decaying charmed baryon.
