Measurement of the B+ and B0 meson lifetimes. Academic Article uri icon

abstract

  • The lifetimes of the B+ and B0 mesons have been measured using fully reconstructed decays. In a sample of 49 600J/+- decays recorded with the Collider Detector at Fermilab, 14816 B+ and 12116B0 mesons have been reconstructed using the silicon vertex detector. Unbinned likelihood fits to the proper lifetime distributions of these B mesons give +=1.610.16 (stat)0.05 (syst) ps, 0=1.570.18 (stat) 0.08 (syst) ps, and +/0=1. 020.16 (stat) 0.05 (syst). 1994 The American Physical Society.
