Tóm tắt

For $$e^ + e^ - \to \bar tt$$ with subsequent semileptonic $$\bar t$$ and nonleptonic $$\bar t$$ decay and vice versa we investigate a few CP-odd observables and evaluate them within Higgs boson and supersymmetric models of CP nonconservation. We find that effects of the order of 0.5% to 3% are possible.
