Abstract

From 1.4 million hadronic Z decays collected by the ALEPH detector at LEP, an enriched sample of Z → cc̄ events is extracted by requiring the presence of a high momentum D*±. The charm quark forward-backward charge asymmetry at the Z pole is measured to be AFB 0.c = (8.0 ± 2.4) % corresponding to an effective electroweak mixing angle of sin2θW eff = 0.2302 ± 0.0054.
