Axion dark matter search with 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 100Hz to 100MHz can be scanned with large sensitivity, corresponding to $f_a$ range of $10^{13} $ GeV $\leq f_a \leq 10^{19}$ GeV the breakdown scale of the global symmetry generating the axion or axion like particles (ALPs).
