DAMA annual modulation from electron recoils
  Plasma dark matter, which arises in dissipative dark matter models, can give
rise to large annual modulation signals from keV electron recoils. Previous
work has argued that the DAMA annual modulation signal could have an
explanation within such a scenario. However, detailed predictions are difficult
due to the inherent complexities involved in modelling the halo plasma
interactions with Earth-bound dark matter. Here, we consider a simple
phenomenological model for the dark matter velocity function relevant for
direct detection experiments, and compare the resulting electron scattering
rate with the new DAMA/LIBRA phase 2 data. We also consider the constraints
from other experiments, including XENON100 and DarkSide-50.
