Photonic Freeze-In
Peter Cox, Matthew J. Dolan, Frederick J. Hiskens
We present a new scenario of freeze-in, where the dark matter is produced exclusively via the annihilation of photons. We study fermionic and scalar dark matter models with a focus…

New Limits on Light Dark Matter-Nucleon Scattering
Peter Cox, Matthew J. Dolan, Joshua Wood
We derive new bounds on hadronically-interacting, sub-GeV mass dark matter. First, we show that one-loop interactions with photons can be sufficient to maintain equilibrium between…
