Axion dark matter search using the storage ring EDM method

Abstract

We propose using a modified storage ring 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 precession frequency and the background axion field oscillation to greatly enhance the sensitivity to it. An axion frequency range of 10−9 Hz to 100 MHz can be scanned with high sensitivity, corresponding to fa range of 1013 GeV ≤ fa ≤ 1030 GeV the breakdown scale of the global symmetry generating the axion or axion like particles (ALPs).
