Abstract

The Ξ_c⁺ lifetime is measured using 9.0 fb^-1 of e⁺e^- annihilation data collected on and just below the Υ(4S) resonance with the CLEO II.V detector at CESR. This is the first measurement of the Ξ_c⁺ lifetime from a collider experiment. Using an unbinned maximum likelihood fit, the Ξ_c⁺ lifetime is measured to be 503 ±47(stat) ± 18(syst) fs. The precision of this measurement is comparable to previous measurements carried out by fixed target experiments with different sources of systematic uncertainties.
