Abstract

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)over bar> --> 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.
