CP NONCONSERVATION
W. Bernreuther (Aachen)

An overview is given, within the standard theory (SM) of electroweak inter- actions and some of its popular extensions, on the phenomenology of CP non- conservation. Emphasis is put on recent developments. The status of SM pre- dictions concerning CP violation in neutral Kaon decays, and the role of B- meson decays in testing the Kobayashi-Maskawa mechanism of CP violation is reviewed. Non-standard CP-nonconserving interactions predicted by multi-Higgs and supersymmetric extensions of the SM are outlined and theoretical ex- pectations for searches of such interactions in the laboratory are discussed. These include a current experiment on CP violation in hyperon decays, searches for permanent electric dipole moments of the neutron and of certain atoms, and present and future searches for CP-nonconserving effects in high-energy re- actions, specifically in the production and decay of top quarks.
