Abstract:

In order to observe a signal of possible CP violation in top-quark couplings, we have studied energy correlation of the final leptons in

e~+e~-\to t\bar{t}\to \ell~+\ell~-X/\ell~\pm X

at future linear colliders. Applying the recently proposed optimal method, we have compared the statistical significances of CP-violation-parameter determination using single- and double-lepton distributions. We have found that the single-lepton distribution analysis is more advantageous.
