QCD corrections to spin correlations in top quark production at lepton colliders - art. no. 014023.

Spin correlations, using a generic spin basis, are investigated to leading order in QCD for top quark production at lepton colliders. Even though thes e radiative corrections induce an anomalous gamma/Z magnetic moment for the top quarks and allow for single real gluon emission, their effects on the top quark spin orientation are very small. The final results are that the t op quarks (or top antiquarks) are produced in an essentially unique spin co nfiguration in polarized lepton collisions even after including the O(alpha (s)) QCD corrections.
