Electric Dipole Moment Measurements at Storage Rings

Abstract

Abstract Electric Dipole Moments (EDM) of elementary particles, including hadrons, are considered as one of the most powerful tools to discover CP-violation beyond the already known sources of the Standard Model. Such CP-violating mechanisms are required to explain the dominance of matter over anti-matter in our universe. Up to now experiments concentrated on neutral systems. Storage rings offer the possibility to measure EDMs of charged particles by observing the influence of the EDM on the spin motion. Different options and a strategy towards storage ring EDM measurements will be discussed.
