Abstract
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
-
couplings.
The off-diagonal spin basis for the top and anti-top quarks
is shown to be useful to probe the anomalous couplings.
