Abstract
We discuss in detail top quark polarization in above-threshold production at a polarized linear collider. We pay particular attention to the minimization and maximization of the polarization of the top quark by tuning the longitudinal polarization of the and beams. The polarization of the top quark is calculated in full next-to-leading order QCD. We also discuss the beam polarization dependence of the longitudinal spin-spin correlations of the top and antitop quark spins.
