Abstract

We analyze spin correlations between top quark and anti-top quark produced at polarized e⁺ e^- and gamma gamma colliders. We consider a generic spin basis to find a strong spin correlation. Optimal spin decompositions for top quark pair are presented for e⁺ e^- and gamma gamma colliders. We show the cross-section in these bases and discuss the characteristics of results.
