Abstract
We obtain analytic formulae for the cross section of the sequential pr ocesses 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 de pendence 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 t he production and the decay are explicitly shown. Different observable s 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.
