Abstract: (Elsevier)

The process of top-quark pair production at future high-energy e + e − linear colliders has been investigated as a possible test of physics beyond the Standard Model. Non-standard interactions have been assumed both for the production and for the subsequent decay of the top quarks. The energy spectrum of the single lepton ℓ ± and the energy correlation of ℓ + and ℓ − emerging from the process e + e − → t t → ℓ ± X/ℓ + ℓ − X are calculated. The energy-spectrum asymmetry of ℓ + and ℓ − is considered as a measure of CP violation. An optimal method to determine whether CP violation occurs in the production or in the decay processes is proposed.
