Description
The storage ring proton electric dipole moment (pEDM) experiment aims to probe the proton EDM with a sensitivity of 10^{-29}\, e \cdot \text{cm}. This effort is complementary to neutron and atomic, molecular, and optical EDM searches, and will constitute the first direct measurement of the proton EDM—improving constraints on \theta_{\text{QCD}} by three orders of magnitude beyond the current best limit. To maximize sensitivity while suppressing systematic uncertainties, the experiment employs several innovative techniques. These include the frozen-spin method with a 0.7 GeV/c magic-momentum proton beam, an all-electric ring with strong magnetic focusing, and counter-rotating beams to cancel dominant systematic effects. In this talk, I will outline the conceptual design and operating principles of the pEDM experiment, highlight recent progress and prototyping efforts at BNL, and discuss the outlook for future developments.
