The Proton EDM Experiment

The storage ring proton electric dipole moment (pEDM) experiment is the first direct search for a proton EDM. It will improve on the current (indirect) limit by at least four orders of magnitude and surpass the current sensitivity (set by neutron EDM experiments) to QCD CP-violation by at least three orders of magnitude. This makes it an extremely sensitive probe of new physics, with major potential to discover the existence of axionic dark matter (and, therefore, solve the Strong CP problem) and find a new source of CP violation to help explain the universe’s matter-antimatter asymmetry.
