摘要：

We find that the CP-violating asymmetry [Gamma(t --> bW(+)) - Gamma(($) over bar t --> ($) over bar bW(-))]/[t --> bW(+)) + Gamma(($) over bar t --> ($) over bar bW(-))] at the one-loop order within the minimal supersymmetric extension of the standard model is of the order of few percent for maximal CP violation. It could be measured by considering the rate difference in the one-lepton events.
