DOWNLOAD EBOOKTwo measurements of the lifetime of neutral and charged B mesons in p{bar p} collisions at √s = 1.8 TeV by the CDF experiment are presented. The first relies on the study of exclusive decays of the type B → [psi] K, the second on semileptonic decays of a B meson into a D° or a D. The combined results are [tau](B+) = 1.62 ± 0.09 ps, [tau](B0) = 1.60 ± 0.09 ps and [tau](B+)/[tau](B°) = 1.00 ± 0.07.
