Title:     Lepton-Flavored Dark Matter

Abstract: It may not be a coincidence that the scales required to "explain" the muon g-2 anomaly and to get the right amount of dark matter in the universe are very similar: about at the electroweak scale, i.e., O(100 GeV - 1 TeV).  However, there are no definitive signs of such new interactions among measurements involving charged leptons nor at experiments directly searching for dark matter.  This may be pointing us to the idea that dark matter interacts minimally with first-generation fermions.  Remarkably, if such electroweak-scale interactions do exist primarily among mu- and tau-flavored leptons, they are consistent with results from direct and indirect searches for dark matter, charged-lepton decays, results from LEP, neutrino trident production, and constraints from the LHC.
