A Storage Ring Experiment to Detect a Proton Electric Dipole Moment
read the original abstract
A new experiment is described to detect a permanent electric dipole moment of the proton with a sensitivity of $10^{-29}e\cdot$cm by using polarized "magic" momentum $0.7$~GeV/c protons in an all-electric storage ring. Systematic errors relevant to the experiment are discussed and techniques to address them are presented. The measurement is sensitive to new physics beyond the Standard Model at the scale of 3000~TeV.

First Experimental Limit on the Permanent Electric Dipole Moment of the Deuteron
First experimental limit on deuteron EDM: |d^d| < 2.5 × 10^{-17} e·cm (95% CL) from observed spin-axis tilts in a magnetic storage ring.

A Quantal Theory of Restoration of Strong CP Symmetry
A mechanism is proposed where the CP violating phase relaxes in discrete steps via nucleation of membranes that discharge the magnetic dual of a 4-form flux, with bubbles colliding and percolating near the chiral symm...
