CP violation in the decays $t \to \ell^+\nu b$ and $\bar t \to \ell^-\bar\nu \bar b$ from the production process $e^-e^+ \to \ttbar$ is discussed. Since the asymmetry proposed as a measure of CP violation vanishes even at the one-loop level…

CP violation is now measured by three numbers: \epsilon and {\epsilon{^{\prime} for the K^{0} system and sin2\beta for B^{0}. A future measurement of the analogue of {\epsilon{^{\prime} for the B system would end any possibility of a…
