Abstract

Using about 1.5 million hadronic Z decays recorded with the aleph detector, the lifetime of the b baryons has been measured using two independent data samples. From a maximum likelihood fit to the impact parameter distribution of leptons in 519 Λℓ^- combinations containing a b baryon sample of 290 decays, the measured b baryon lifetime is τ_b-baryon = 1.05_-0.11 ^+0.12(stat)±0.09(syst) ps. The lifetime of the Λ_b ⁰ baryon from a maximum likelihood fit to the proper time distribution of 58 Λ_c ⁺ℓ^- candidates containing a Λ_b ⁰ sample of 44 decays, is τ_{Λ_b ⁰} = 1.02_-0.18 ^+0.23(stat) ± 0.06(syst) ps.

N2 - Using about 1.5 million hadronic Z decays recorded with the aleph detector, the lifetime of the b baryons has been measured using two independent data samples. From a maximum likelihood fit to the impact parameter distribution of leptons in 519 Λℓ- combinations containing a b baryon sample of 290 decays, the measured b baryon lifetime is τb-baryon = 1.05-0.11 +0.12(stat)±0.09(syst) ps. The lifetime of the Λb 0 baryon from a maximum likelihood fit to the proper time distribution of 58 Λc +ℓ- candidates containing a Λb 0 sample of 44 decays, is τΛb 0 = 1.02-0.18 +0.23(stat) ± 0.06(syst) ps.
