摘要：

Measurements of the forward-backward production asymmetry of heavy quarks in Z decays provide a precise determination of sin2θleptW,eff. The asymmetries are sensitive to QCD effects, in particular hard gluon radiation. In this paper QCD corrections for Abb̄FB and Acc̄FB are discussed. The interplay between the experimental techniques used to measure the asymmetries and the QCD effects is investigated using simulated events. A procedure to estimate the correction needed for experimental measurements is proposed, and some specific examples are given.
