SUMMARY:Muon g-2 Experiments as Dark Matter Detectors\, Theory Seminar
  (High Energy/Cosmology)\, Ryan Janish\, Fermilab
DESCRIPTION:We propose extending the search for dark matter (DM) by us
 ing muon spin targets.  An ultralight DM background may apply an oscil
 lating torque to muon spins\, resulting in novel precession trajectori
 es.  A time-resolved reanalysis of muon precession data from the ongoi
 ng Fermilab g-2 experiment and from future g-2 and EDM measurements is
  sensitive to this signal.  We place constraints on DM-muon interactio
 ns using existing data\, and outline the detection reach of a dedicate
 d re-analysis.  In addition\, some DM candidates alter precession prim
 arily through a shifted precession frequency\, i.e. they provide an ap
 parent contribution to the muon magnetic dipole moment which depends o
 n the local DM density.  We find that the current muon g-2 anomaly can
  be explained by pseudoscalar DM which induces an oscillating electric
  dipole moment for the muon.  This explanation may be verified with a 
 time-resolved analysis.
