Lepton-flavored dark matter

In this work, we address two paradoxes. The first is that the measured dark-matter relic density can be satisfied with new physics at O(100 GeV–1 TeV)O(100 GeV–1 TeV), while the null results from direct-detection experiments place lower bounds of O(10 TeV)O(10 TeV) on a new-physics scale. The second puzzle is that the severe suppression of lepton-flavor-violating processes involving electrons, e.g. μ→3eμ→3e, τ→eμμτ→eμμ, etc., implies that generic new-physics contributions to lepton interactions cannot exist below O(10–100 TeV)O(10–100 TeV), whereas the 3.6σ   deviation of the muon g−2g−2 from the standard model can be explained by a new-physics scale
