Towards a facility at COSY to measure permanent electric dipole moments

COSY has a history of highly successful operation of cooled beams and internal targets both with and without polarization and as such it constitutes a unique facility for hadronic probes on a world-wide scale. Starting from meson production and nucleon-nucleon scattering more and more experience in polarized beam/target manipulation and polarimetry is gained. Extending polarization physics to antiprotons requires pre-studies at COSY to be continued at the antiproton decelerator AD at CERN. As a long-term perspective, the search for electric dipole moments of the proton, deuteron, and 3He in a dedicated storage ring could provide a new method to push the limits in the quest for CP violation searches beyond the Standard Model.
