摘要：

The polarization dependent momentum distributions of top quarks and their decay products are calculated for t ($) over bar t production at future e(+)e(-) colliders with polarized beams. The Green function formalism is applied to this reaction near energy threshold. The Lippmann-Schwinger equations for the S-wave and P-wave Green functions are solved numerically for the QCD chromostatic potential given by the two-loop formula at large momentum transfers and Richardson ansatz at intermediate and small ones. It is demonstrated that for the longitudinally polarized electron beam an optimally polarized sample of top quarks can be produced.
