| Summary:
We introduce Super-Resonant Dark Matter, a model of self-interacting dark
matter based on the low energy effective theory of supersymmetric QCD. The
structure of the theory ensures a resonant enhancement of the self-interactions
of the low energy mesons, since their mass ratio is set by the number of colors
and flavors. The velocity dependence of the resonantly enhanced
self-interactions allows such theories to accommodate puzzles in small scale
structure that arise from dark matter halos of different sizes. The dark matter
mass is then predicted to be around 3-4 MeV, with its abundance set by
freeze-in via a kinetically mixed dark photon.
