Dark, chiral fermions carrying lepton flavor quantum numbers are natural candidates for freeze-in.Small couplings with the Standard Model fermions of the order of lepton Yukawas arise naturally in the limit of Minimal Flavor Violation.Particles with certain representations under the flavor group are rendered automatically stable when interactions conserve the total lepton number.For masses in the GeV-TeV range, the minimal representation with three flavors leads to signals at future direct detection experiments like LZ and DARWIN.Interestingly, freeze-in with a smaller flavor group such as SU(2) is already being probed by XENON1T.This is based on a talk presented at XXIV DAE-BRNS HEP Symposium.
