摘要：

We obtain analytic formulae for the cross section of the sequential processes of e(+)e(-) --> t (t) over bar and t --> bl(+)v/(t) over bar --> (b) over bar l(-)(v) over bar in the laboratory frame, where the dependence on triple product correlations of the type ((q) over cap(1) x (q) over cap(2) . (q) over cap(3)), induced by CP violation both in the production and the decay are explicitly shown. Different observables sensitive to CP violation are defined and calculated in the Minimal Supersymmetric Standard Model (MSSM). The observables sensitive to CP violation are of the order of 10(-3). The dependence on the masses of the supersymmetric particles is also shown.
