Axionlike dark matter search using the storage ring EDM method

Abstract

We propose using the storage ring electric dipole moment (EDM) method to search for the axion dark matter induced EDM oscillation in nucleons. The method uses a combination of B and E fields to produce a resonance between the g − 2 spin precession frequency and the background axion field oscillation to greatly enhance sensitivity to it. An axion frequency range from 10−9 Hz to 100 MHz can, in principle, be scanned with high sensitivity, corresponding to an fa range of 1013 GeV ≤ fa ≤ 1030 GeV, the breakdown scale of the global symmetry generating the axion or axionlike particles. c.Published by the American Physical Society
