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 5 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 potentially the most promising effort to solve the strong CP problem. This makes it manifestly one of the most important probes for the existence of axions (with important consequences for dark matter searches), CP-violation in the Higgs sector and the source of the universe’s matter-antimatter asymmetry. These, 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.
