Abstract
In order to observe a signal of possible CP violation in top-quark cou plings, we have studied the energy correlation of the final leptons in e(+)e(-) --> t (t) over bar --> l(+)l(-)X/l(+/-)X at future linear co lliders, Applying the recently-proposed optimal method, we have compar ed the statistical significances of CP-violation-parameter determinati on using double- and single-lepton distributions. We have found that t he single-lepton-distribution analysis is more advantageous.
