Description
We study new physics scenarios that resolve the muon (g − 2)μ anomaly with only Standard Model singlet particles coupled to muons. Since such models are only viable in the MeV – TeV mass range and require sizable muon couplings, they predict abundant accelerator production through the same interaction that resolves the anomaly. We show that B-factories and high energy colliders can respectively probe the middle (0.1 - 10 GeV) and high mass (>10 GeV) regions of viable single masses. Searches for light singlets (<0.1 GeV) are better suited for fixed target experiments. We show that a combination of these experiments can cover nearly all viable singlets scenarios, independently of their decay modes.
