Abstract

Polarization studies for heavy quarks can lead to important tests of the Standard Model. Top quark pair production in e(+)e(-) annihilationis considered near energy threshold. It is shown that for longitudinally polarized electrons the produced top quarks and antiquarks are highly polarised. Dynamical effects originating from strong interactions in the t - ($) over bar t system can be calculated using Green function method. Energy-angular distributions of leptons in semileptonic decays of polarized heavy quarks are sensitive to both the polarisation ofthe decaying quark and V-A structure of the weak charged current. Some applications to b quark physics at the Z(0) resonance are briefly reviewed.
