====== TTP97-45 Top Quark Pair Production and Decay Near Threshold in        e+e- Collisions ======
 
 
   <hidden TTP97-45  Top Quark Pair Production and Decay Near Threshold in        e+e- Collisions > We review the physics involved in the production and decay of top quarks in
 e^+e^- -> ttbar 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 free polarized top quarks, and thus it can be
 calculated without bound-state effects or the final-state interactions.
