Top quarks and CP violation in polarized e⁺e⁻ collisions

Abstract

Electroweak dipole moments of the top quark are conjectured and their effect in polarized e⁺e⁻ collisions is examined for the expectation values of two different CP-odd observables. One of these observables probes the real part of the dipole moments whereas the other probes their imaginary part. It turns out that varying the polarization of the electron beam substantially enhances the resolving power of the experiment.
