Description
The storage ring electric dipole moment (EDM) experiment is designed to probe one of the most profound mysteries in fundamental physics: the origin of CP violation beyond the Standard Model and its possible role in explaining the observed matter-antimatter asymmetry of the universe. By aiming to measure the proton EDM with a sensitivity of $10^{−29}\,e⋅{\rm cm}$, this experiment will improve the current limit on hadronic EDMs by more than three orders of magnitude and directly address the strong CP problem. The method builds upon the renowned muon g-2 storage ring technique, adapting it for EDM measurements through refined control of beam and spin dynamics. Drawing on decades of expertise from the muon g-2 program—including precision field control, spin tracking, and advanced instrumentation—this approach provides a technically mature and highly sensitive platform to explore new sources of CP violation. The expected sensitivity corresponds to probing New Physics at energy scales up to order of $10^3$ TeV, offering a unique and complementary window into physics beyond the Standard Model.
