Probing CP Violation via Top Polarization at NLC

Abstract

Possible $CP$-violation in top-quark couplings is discussed. It is shown that the lepton-energy distributions in $e^{+}{e}^{-}\to t\bar{t}\to {\ell }^{+}{\ell }^{-}X/{\ell }^{\pm }X$ at next linear colliders (NLC) could give us useful information for this study. The statistical significance of $CP$-violating-parameter determination is estimated.
