摘要：
We discuss top quark production and its subsequent decay as used for searching new physics at lepton colliders. The angular dependence of the decay leptons is calculated including both QCD corrections and anomalous gamma /Z-t (t) over bar couplings. The oh-diagonal spin basis for the top and anti-top quarks is shown to be useful to probe the anomalous couplings.
