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.Comment: 6 pages, 5 postscript figues, submitted to BCP4 proceeding
