摘要：

We have measured the forward-backward asymmetry in Z0-->bbBAR decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events square-root s almost-equal-to M(Z). From a fit to the single and dilepton p and p perpendicular-to spectra, we determine A(bbBAR) = 0.130(-0.042)+0.044 including the correction for B0-BBAR0 mixing.
