We have measured the forward-backward asymmetry in e+e-→ b overlineb and e +e-→ c overlinec processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z 0. From a fit to the single lepton and dilepton p and pT spectra, we determine A b overlineb=0.086±0.015±0.007 and A c overlinec=0.083±0.038±0.027 at the effective center-of-mass energy √ s=91.24 GeV. These measurements yield a value of the electroweak mixing angle sin2overlineθw=0.2336±0.0029 .
