Abstract
The lifetime of the baryons is measured using the semileptonic decay, where decay to . The data sample consists ofof p pbar collisions at √s = 1.8 TeV, collected by the CDF detector at the Fermilab Tevatron collider during 1992-1995. From a fit to the decay length distribution from the 57 ± 12 events, the lifetime of the is measured to be ps
