Muon g-2 and EDM experiments as muonic dark matter detectors
  The detection of ultralight dark matter through interactions with nucleons,
electrons, and photons has been explored in depth. In this work we propose to
use precision muon experiments, specifically muon g-2 and electric dipole
moment measurements, to detect ultralight dark matter that couples
predominantly to muons. We set direct, terrestrial limits on DM-muon
interactions using existing g-2 data, and show that a time-resolved reanalysis
of ongoing and upcoming precession experiments will be sensitive to dark matter
signals. Intriguingly, we also find that the current muon g-2 anomaly can be
explained by a spin torque applied to muons from a pseudoscalar dark matter
background that induces an oscillating electric dipole moment for the muon.
This explanation may be verified by a time-resolved reanalysis.
