Abstract

The lifetime of Lambda(b)(0) is measured using the semileptonic decay Lambda(b)(0)-->Lambda(c)(+)l(-)nu(-), where the Lambda(c)(+) is reconstructed through its decay Lambda(c)(+) --> pK(-)pi(+). The data were collected by the CDF detector at the Tevatron Collider during 1992-1995 and correspond to an integrated luminosity of 110 pb(-1) of collisions at root s=1.8 TeV. From a fit to the decay length distribution of the Lambda(c)-lepton system from 197+/-25 signal events, the lifetime of Lambda(b)(0) is measured to be 1.32+/-0.15+/- 0.07 ps.
