Abstract

A total of about 900000 Z0 --> qqBAR decays have been analyzed to measure the B0 - B0BAR mixing probability. Two different b tagging techniques have been used: events with two leptons and events with one lepton and one LAMBDA. From a combination of the two methods the average mixing parameter, chi, was determined to be (12.1 +/- 1.6(stat.) +/- 0.4(syst.) +/- 0.4(model))%.
