Freeze-in dark matter via lepton portal: Hubble tension and stellar cooling
Abstract We propose a new freeze-in dark matter candidate which feebly couples to the standard model charged leptons. The feeble interactions allow it (i) to freeze-in from the Standard Model thermal bath with its relic density being either a fraction or the entirety of the observed dark matter dens...
