Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon Ξc0 using the decay channels Ξc0 → Ξ-π+ and Ξc0 → Ω-K+. From a combined sample of 110 ± 17 events we find τ (Ξc0) = 118-12+14 ± 5 fs, where the first and second errors are statistical and systematic, respectively.

Abstract

Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon Ξc0 using the decay channels Ξc0 → Ξ-π+ and Ξc0 → Ω-K+. From a combined sample of 110 ± 17 events we find τ (Ξc0) = 118-12+14 ± 5 fs, where the first and second errors are statistical and systematic, respectively.
