Abstract

Results on B0−View the MathML source0 mixing in e+e− annihilation at LEP are reported. A new method is used, where the charge of one b quark is tagged by a high-p, high-p⊥ electron or muon, and the charge of the other is extracted from the momentum-weighted average of the charges of jet fragments. Based on the analysis of 180 000 hadronic Z decays produced in the ALEPH detector, View the MathML source is obtained. Combining this result with the ALEPH dipleton measurement yields χ=0.129±0.022.
