Description
Fermionic dark matter is added to the Froggatt-Nielsen mechanism, and conditions for freezeout identified. DM is charged under $U(1)_{FN}$, with the dominant annihilation channel a CP-even flavon $+$ CP-odd flavon. When the DM-flavon coupling strength $\sim$ the Cabibbo angle (0.23): (1) the DM mass is $\mathcal{O}$(100 GeV - 1 TeV), (2) perturbativity puts a lower and upper limits on the flavor scale,
(3) DM is a secluded WIMP effectively hidden from collider and direct detection searches.
Low-energy flavor experiments limiting the masses of dark matter and mediators constitute the best constraints on this scenario, while Fermi-LAT observations of dwarf galaxies, and collider searches for missing energy plus a single jet/bottom/top, are promising avenues for future discovery.
