Precision Storage Rings for Electric Dipole Moment Searches: A Tool En Route to Physics Beyond-the-Standard-Model

Electric Dipole Moments (EDM) of particles (leptons, nucleons, and light nuclei) are currently deemed one the best indicators for new physics, i.e., phenomena which lie outside Standard Model (SM) elementary particle physics—so-called physics “Beyond-the-Standard-Model” (BSM). Since EDMs SM vanishingly small, a finite permanent EDM would indicate charge-parity (CP) symmetry violation in addition to well-known sources SM, could explain baryon asymmetry Universe, while an oscillating hint at possible Dark Matter (DM) field comprising axions or axion-like (ALPs). A approach exploiting polarized charged (proton, deuteron, 3He) precision storage rings offers prospect push current experimental upper limits significantly further, including possibility discovery. In this paper, we describe scientific background steps towards realization ring, will make such measurements possible.
