The storage ring proton electric dipole moment (EDM) experiment (pEDM) will be the first direct search for a proton EDM and will improve on the current (indirect) limit by at least 4 orders of magnitude. It will therefore surpass the current sensitivity (set by neutron EDM experiments) to QCD CP-violation by 3 orders of magnitude, making it one of the promising searches for the source of the universe’s matter-antimatter asymmetry. It is an extremely sensitive probe for the existence of axions with important consequences for dark matter searches, therefore making it one of the most promising efforts to solve the strong CP problem. These motivators, coupled with a new Physics reach of O(10^3) TeV and a construction cost of O(£100M), make it one of the low-cost/high-return proposals in particle physics today. The experiment will build upon the highly successful techniques of the Muon g-2 Experiment at Fermilab, which the UK has been a leading contributor to. In this talk, I will motivate and describe the pEDM experiment, and detail how the UK can play a leading role in making it a success by building upon its vast expertise and recent achievements.
