Electric Dipole Moment Measurements at Storage Rings (2203.12014v1)
Published 22 Mar 2022 in hep-ex and physics.acc-ph
Abstract: Electric Dipole Moments (EDMs) of subatomic particles, are considered as one of the most powerful tools to study CP-violation beyond the Standard Model. Such CP-violating mechanisms are searched for to explain the dominance of matter over anti-matter in our universe. This paper discusses EDM searches of charged hadrons in storage rings. The document focuses on activities at the existing storage ring COSY at Forschungszentrum J\"ulich, Germany and the design of a 100\,m circumference prototype ring able to demonstrate key technologies and components. These include simultaneous clockwise and counter-clockwise beam operation with electrostatic bending elements and, by adding a magnetic field, the frozen spin technique.
