摘要

The B-0-(B) over bar (0) oscillation frequency has been measured with a sample of 23x10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we select events in which both B mesons decay semileptonically and use the charge of the leptons to identify the flavor of each B meson. A simultaneous fit to the decay time difference distributions for opposite- and same-sign dilepton events gives Deltam(d)=0.493+/-0.012(stat )+/-0.009(syst) ps(-1) .
