Abstract

We discuss the polarization of top quarks produced at a polarized linear e⁺ e^- collider. Close-to-maximal values of the top quark polarization can be achieved with longitudinal beam polarizations (h_- = -0.80, h₊ = +0.625) or (h_- = +0.80, h₊ = -0.625) at intermediate beam energies. The option (h_- = -0.80, h₊ = +0.625) has to be preferred since this choice is quite stable against variations of the beam polarization. All our quantitative results have been obtained at NLO QCD.
