Azimuthal angular dependence of decay lepton in e+ e- --> t tbar

High Energy Physics - Phenomenology 2009-01-07 v1

Abstract

We discuss top quark production and its subsequent decay 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 tbar couplings. The off-diagonal spin basis for the top and anti-top quarks is shown to be useful to probe the anomalous couplings.
