Description

Axions in the local dark matter halo of the galaxy collide with virtual photons dressing the electromagnetic vertex of the muon. The collisions shift the muon magnetic moment in a way that scales with the volume of the muon beam and transforms like the axion under the charge conjugation, parity, and time-reversal symmetries of quantum electrodynamics. Analysis of measurements of the muon magnetic moment suggests that axions saturate the local halo density.
