Abstract

We discuss in detail top quark polarization in above-threshold (t (t) over bar) production at a polarized linear e(+)e(-) collider. We pay particular attention to the minimization and maximization of the polarization of the top quark by tuning the longitudinal polarization of the e(+) and e(-) 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.
