We report on a measurement of the Omega(0)(c) lifetime using Omega(0)(c) -> Omega(-) pi(+) decays reconstructed in e(+)e(-) -> c (c) over bar data collected by the Belle II experiment and corresponding to 207 fb(-1) of integrated luminosity. The result, tau(Omega(0)(c)) = 243 +/- 48(stat) +/- 11(syst) fs, agrees with recent measurements indicating that the Omega(0)(c) is not the shortest-lived weakly decaying charmed baryon.

Abstract
We report on a measurement of the Omega(0)(c) lifetime using Omega(0)(c) -> Omega(-) pi(+) decays reconstructed in e(+)e(-) -> c (c) over bar data collected by the Belle II experiment and corresponding to 207 fb(-1) of integrated luminosity. The result, tau(Omega(0)(c)) = 243 +/- 48(stat) +/- 11(syst) fs, agrees with recent measurements indicating that the Omega(0)(c) is not the shortest-lived weakly decaying charmed baryon.File in questo prodotto:
