Optimal-observable analysis of the angular and energy distributions for top-quark decay products at polarized linear colliders Original Research Article

An optimal-observable analysis of the angular and energy distributions of the leptons and bottom quarks in the process e+e−→tt̄→l±/(−)b⋯ has been performed in order to measure the most general top-quark couplings to gauge bosons at polarized linear colliders. The optimal beam polarization for determination of each coupling has been found. A very sensitive test of CP violation in tt̄ production and decay has been proposed.
