摘要：

We have observed B0-BBAR0 mixing in Z0-->bbBAR decays using hadronic events containing dileptons. The data sample corresponds to 118 200 hadron events at square-root s almost-equal-to M(Z). From a fit to the dilepton p and p perpendicular-to spectra, we determine the mixing parameter to be chi-B = 0.178(-0.040)+0.049.
