摘要：
The B-0(B) over bar (0) oscillation frequency Deltam(d) has been measured with the BaBar detector at the PEP-II asymmetric B factory with different experimental techniques. The discussion here is focused on the recent simultaneous measurement of Deltam(d) and tau(B)o with exclusively reconstructed B-0 D*(-)l(+)v(i) decays, based on 23 million B (B) over bar pairs collected by BaBar. The measurements Of Deltam(d) with fully reconstructed hadronic decays and with dilepton events are also reviewed. The average BaBar result is Deltam(d) = 0.500 +/- 0.008 +/- 0.006 ps(-1).
