Four-Fermi Effective Operators in Top-Quark Production and Decay

Abstract

Effects of four-Fermi-type new interactions are studied in top-quark pair production and their subsequent decays at future e^+e^- colliders. Secondary-lepton-energy distributions are calculated for arbitrary longitudinal beam polarizations. An optimal-observables procedure is applied for the determination of new parameters.

Polarized e^- plus unpolarized e^+ collisions were included
