Abstract

We have measured the forward-backward asymmetry in e+e- --> bbBAR and e+e- --> ccBAR processes using hadronic events containing muons or electrons. The data sample corresponds to 410 000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and p(T) spectra, we determine A(bbBAR) = 0.086+/-0.015+/-0.007 and A(ccBAR) = 0.083+/-0.038+/-0.027 at the effective center-of-mass energy square root s = 91.24 GeV. These measurements yield a value of the electroweak mixing angle sin2theta(W)BAR = 0.2336+/-0.0029.
