标题： B Mixing and Lifetime Measurements with the BaBar Detector

摘要： 近期BaBar对B介子的寿命和混合的测量报告如下。 采用的各种技术包括从完全重建有hadronic B衰变到部分重建技术，再到完全包容的方法使用双轻子事件。 所呈现的结果基于BaBar在1999-2000年数据采集期间收集的数据样本，并应被视为初步结果。 显示英文摘要

摘要： Recent BaBar measurements on lifetime and mixing of B mesons are reported. Various techniques are used, ranging from the full reconstruction of hadronic B decays, to partial reconstruction techniques, and to a totally inclusive approach with dilepton events. The results presented are based on a data sample collected by BaBar during the 1999-2000 data taking, and should be considered as preliminary.
