We study the dark matter phenomenology of Standard Model extensions addressing the reported anomaly in the $$R_K$$ R K observable at one-loop. The article covers the case of fermionic singlet DM coupling leptophilically, quarkphilically or amphiphilically to the SM. The setup utilizes a large coupling of the new particle content to the second lepton generation to explain the $$R_K$$ R K anomaly, which in return tends to diminish the dark matter relic density. Further, dark matter…

If a small fraction of the dark matter has a mini-charge, a million times smaller than the charge on the electron, and a mass in the range of 1–100 times the electron mass, then the data from the EDGES experiment can be explained while remaining consistent with all other observations.
