Abstract

The lifetime of Λ⁰ _b is measured using the semileptonic decay Λ⁰ _b → Λ⁺ _cℓ⁻ν⁻, where the Λ⁺ _c is reconstructed through its decay Λ⁺ _c → pK⁻ π⁺. The data were collected by the CDF detector at the Tevatron Collider during 1992–1995 and correspond to an integrated luminosity of 110pb⁻¹ of pp collisions at √s = 1.8 TeV. From a fit to the decay length distribution of the Λ_c-lepton system from 197 ± 25 signal events, the lifetime of Λ⁰ _b is measured to be 1.32 ± 0.15 ± 0.07 ps.
