| 概要 | K. Abe, S. Okuno, et al. [Belle Collaboration] , The lifetimes of the {B}0 and B- mesons are extracted from 29.1fb-1 of data collected with the Belle detector at the KEK B factory. A fit to the decay length differences of neutral and charged B meson pairs, measured in events where one of the B mesons is fully reconstructed in several hadronic modes, yields τ{B}0 = 1.554±0.030 (stat)±0.019 (syst)ps, τB- = 1.695±0.026 (stat)±0.015 (syst)ps, and τB- / τ{B}0 = 1.091±0.023 (stat)±0.014 (syst). |
