Measurement of the B+ and B0 meson lifetimes


Journal Article

The lifetimes of the B+ and B0 mesons have been measured using fully reconstructed decays. In a sample of ∼49 600J/ψ→μ+μ- decays recorded with the Collider Detector at Fermilab, 148±16 B+ and 121±16B0 mesons have been reconstructed using the silicon vertex detector. Unbinned likelihood fits to the proper lifetime distributions of these B mesons give τ+=1.61±0.16 (stat)±0.05 (syst) ps, τ0=1.57±0.18 (stat) ±0.08 (syst) ps, and τ+/τ0=1. 02±0.16 (stat) ±0.05 (syst). © 1994 The American Physical Society.
