Measurement of Heavy Quark Forward-Backward Asymmetries and Average B Mixing Using Leptons in Hadronic Z Decays
The OPAL collaboration, G. Abbiendi
Abstract
Hadronic Z0 decays with identified electrons or muons have been used to measure the forward-backward asymmetries of e+e- --> Z0 --> bbbar and e+e- --> Z0 --> ccbar events. The asymmetries at three centre-of-mass energies, and the average B mixing parameter, chi, are determined in a simultaneous fit to events with one or two lepton candidates.
