Title: Lepton-flavored dark matter

Abstract

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), while the null results from direct-detection experiments place lower bounds of 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 → 3e, τ → eμμ, etc., implies that generic new-physics contributions to lepton interactions cannot exist below O(10–100 TeV), whereas the 3.6σ deviation of the muon g-2 from the standard model can be explained by a new physics scale ⁺ecolliders. We suggest experimental tests for these ideas at colliders and for low-energy observables. (author)
