Storage ring proton EDM experiment at 10^{-29} e.cm

The storage ring proton EDM experiment aims to measure the electric dipole moment (EDM) of the proton at 10^{-29} e.cm, which is a three orders of magnitude improvement from the current best limit of the neutron EDM. This experiment will provide competitive sensitivity to New Physics up to 1,000 TeV. With the frozen-spin condition in a hybrid electric and magnetic storage ring, the polarization of stored protons will rotate in the vertical direction in the presence of the EDM. The known systematic error sources, such as radial magnetic field, vertical electric field, and vertical velocity effect, can be suppressed below the target sensitivity thanks to the latest symmetric lattice design. We consider this experiment ready to go and have asked for a strong endorsement from the community at the 2022 Seattle Snowmass meeting.
