Bounds on Cosmic Ray-Boosted Dark Matter in Simplified Models and its
  Corresponding Neutrino-Floor
  We study direct detection bounds on cosmic ray-upscattered dark matter in
simplified models including light mediators. We find that the energy dependence
in the scattering cross section is significant, and produces stronger bounds
than previously found (which assumed constant cross sections) by many orders of
magnitude at low DM mass. Finally, we compute the "neutrino-floor" that will
limit future direct detection searches for cosmic ray-upscattered dark matter.
While we focus on vector interactions for illustration, we emphasize that the
energy dependence is critical in determining accurate bounds on any particle
physics model of Dark Matter-CR interactions from experimental data on this
scenario.
