Abstract
We report a measurement of the lifetime of the baryon in decays to the final state in a sample corresponding to collected in collisions at by the CDF II detector at the Tevatron collider. Using a sample of about 3000 fully reconstructed events we measure (corresponding to , where is the speed of light). The ratio of this result and the world average lifetime yields (stat) and (syst), in good agreement with recent theoretical predictions.
