      abstract     = {The Standard Model (SM) of Particle Physics is not capable
                      to account for the apparent matter-antimatter asymmetry of
                      our Universe. Physics beyond the SM is required and is
                      either probedby employing highest energies (e.g., at LHC),
                      or by striving for ultimate precision and sensitivity(e.g.,
                      in the search for electric dipole moments). Permanent
                      electric dipole moments (EDMs) of par-ticles violate both
                      time reversal (T) and parity (P) invariance, and are via the
                      CPT-theorem alsoCP-violating. Finding a non-zero EDM would
                      be a strong indication for physics beyond the SM, andpushing
                      upper limits further provides crucial tests for any
                      corresponding theoretical model. Up tonow, EDM searches
                      focused on neutral systems (neutrons, atoms, and molecules).
                      Storage rings,however, offer the possibility to measure EDMs
                      of charged particles by observing the influence ofthe EDM on
                      the spin motion in the ring. Direct searches of proton and
                      deuteron EDMs bear thepotential to reach sensitivities
                      beyond 1E-29 e cm.Since the Cooler Synchrotron COSY at the
                      Forschungszentrum Jülich provides polarized protonsand
                      deuterons up to momenta of 3.7 GeV/c, it constitutes an
                      ideal testing ground and starting pointfor such an
                      experimental program. The collaboration is presently aiming
                      at a first direct (precursor)measurement of the deuteron EDM
                      in COSY, using an RF Wien filter that was specifically
                      designedfor that purpose. Beyond that, the technical design
                      of a prototype EDM storage ring constitutes thenext major
                      milestone of the JEDI research program, which shall be
                      addressed together with CERN inthe framework of a newly
                      formed CPEDM collaboration (Charged Particle Electric Dipole
                      Momentcollaboration).The talk will present the JEDI plans
                      for the measurement of proton and deuteron EDMs, and
                      discussthe various technical developments, and also show
                      recent results.This work is supported by an ERC
