Descripción
Supersymmetric models contain new sources of CP violation if the parameters are complex. These new phases lead to important effects in production and decay processes of SUSY particles. They also might strongly affect the Higgs sector. We discuss some of these effects. In particular, we concentrate on CP violating observables: triple product and decay rate asymmetries. The triple product asymmetries usually involve spin correlations between production and decay and already appear at tree level. We discuss these in chargino and neutralino production and decay. The decay asymmetries are due to loop effects. We calculate such asymmetries for H± and chargino decays.
