CP-violating asymmetries in top-quark production and decay in e+e− annihilation within the MSSM Original Research Article

We obtain analytic formulae for the cross section of the sequential processes of e+e− → tt and t → bl+v / t → bl−v in the laboratory frame, where the dependence on triple product correlations of the type (q̂1 × q̂2 · q̂3 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.
