Fermion polarization in sfermion decays as a probe of CP phases in the MSSM

The longitudinal polarization of fermions (tops and taus) produced in sfermion decays to neutralinos or charginos can be a useful tool for the determination of SUSY parameters. We discuss this fermion polarization in the context of the MSSM with complex parameters. We show that the dependence on CP-violating phases can be large and that the fermion polarization may hence be used as a sensitive probe of CP phases in the MSSM.

Electroweak dipole moment form factors of the top quark in supersymmetry

Abstract The CP violating electric and weak dipole moment form factors of the top quark, dγ(s) and dZ(s), appear in the process e + e - → t t . We present a complete analysis of these dipole moment form factors within the minimal supersymmetric standard model with complex parameters. We include gluino, chargino, and neutralino exchange in the loop of the γt t and Zt t vertex. We give the analytic expressions and present numerical results.
