    Abstract: 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 τB¯0=1.554±0.030(stat)±0.019(syst)ps, τB−=1.695±0.026(stat)±0.015(syst)ps, and τB−/τB¯0=1.091±0.023(stat)±0.014(syst).
