Description
In this work, we try to simultaneously address two puzzles related to dark matter and flavor. The first is tension between the new physics scale suggested by the measured dark-matter relic density, O(100 GeV - 1 TeV), and the null results from direct-detection experiments which suggest a lower bound on the new physics scale of O(10 TeV). The second is tension between the strong constraints on lepton-flavor-violating processes involving electrons and the 3.6-sigma deviation of the muon g-2 from the standard model expectation which suggests a new-physics scale < O(1 TeV). Here, we suggest that these may be related. We consider a gauged lepton-flavor interaction coupling at tree level only to mu- and tau-flavored leptons and the dark sector. Dark matter thus has loop-suppressed couplings to quarks and electrons. We find that a gauged flavor interaction at a scale O(100 GeV - 1 TeV) can be compatible with the muon g-2, the relic density, direct detection, indirect detection, charged-lepton decays, neutrino trident production, and results from hadron and e+e- colliders.
