MEASUREMENT OF THE B(0)-(B)OVER-BAR(0) MIXING PARAMETER AND THE Z-]B(B)OVER-BAR FORWARD-BACKWARD ASYMMETRY

Abstract:

We have measured the time integrated B0B0 mixing parameter and the forward-backward asymmetry in the process e+e- → bb using hadronic events containing muons or electrons. The data sample corresponds to 1,044,000 hadronic decays of the Z. From a fit to the momentum and transverse momentum distributions for single lepton and dilepton events, we have determined the B0B0 mixing parameter to be χB = 0.123 ± 0.012 (stat.) ± 0.008 (sys.), and the bb forward-backward asymmetry at the effective cente...
