Searching for an Electric Dipole Moment using a Storage Ring


    The observation of an electric dipole moment (EDM) by searches currently being developed would be a signal of a new source of CP-violation not present in the Standard Model of particles and forces.
        This talk will present a proposal to search for an EDM using polarized beams (muons, deuterons, or protons) circulating in a storage ring.  The electric field in the particle frame
arising from the motion through the magnetic field (v x B) would, if an EDM were present, generate a small precession observable by sensitive polarimeters.

       Two schemes will be discussed for enhancing the EDM signal in the presence of the magnetic moment precession of the stored particles.
