Abstract
The Xi_c+ lifetime is measured using 9.0 fb^{-1} of e+ e- annihilation data collected on and just below the Upsilon(4S) resonance with the CLEO II.V detector at CESR. The Xi_c+ lifetime is measured using an unbinned maximum likelihood fit. The preliminary result for the Xi_c+ lifetime is (503 +- 47 (stat.) +- 18 (syst.)) fs.
