摘要：

Top quark pairs are produced with strongly correlated spins in the partonic reactions <q(q)over bar>--><t(t)over bar> and gg--<<t(t)over bar>. A complete description of these effects in terms of the spin density matrix of the <t(t)over bar> system in leading order QCD is given. We further discuss the prospects to observe the spin-spin correlations at <p(p)over bar> and pp colliders by measuring suitable angular correlations among the t and (t) over bar decay products.
