Abstract

Using data collected by the Fermilab experiment FOCUS, we measure the lifetime of the charmed baryon Ξ_c⁰ using the decay channels Ξ_c⁰ → Ξ^-π⁺ and Ξ_c⁰ → Ω^-K⁺. From a combined sample of 110 ± 17 events we find τ (Ξ_c⁰) = 118_-12⁺¹⁴ ± 5 fs, where the first and second errors are statistical and systematic, respectively.
