Sub-MeV Dark Sink Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Evan Petrosky +1
A Dark Sink uses dark-sector interactions to siphon energy from dark matter to lighter dark degrees of freedom, i.e. dark radiation. Here, we extend dark matter models containing a…

Dark Matter Catalyzed Baryon Destruction
Yohei Ema, Robert McGehee, Maxim Pospelov +1
WIMP-type dark matter may have additional interactions that break baryon number, leading to induced nucleon decays which are subject to direct experimental constraints from proton…

A Dark Sink Enhances the Direct Detection of Freeze-in Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Aaron Pierce
We describe a simple dark sector structure which, if present, has implications for the direct detection of dark matter (DM): the Dark Sink. A Dark Sink transports energy density fr…
