Abstract

We review the physics involved in the production and decay of top quarks in e(+)e(-) --> t (t) over bar near threshold, with special emphasis on the recent theoretical study on the decay process of top quarks in the threshold region. The energy-angular distribution of l(+) in semileptonic top decays is calculated including the full O(alpha(s)) corrections. Various effects of the final-state interactions are elucidated. A new observable is defined near threshold, which depends only on the decay of fr ee polarized top quarks, and thus it can be calculatedwithout bound-state effects or the final-state interactions.
