Dama annual modulation from electron recoils [CL]

http://arxiv.org/abs/1804.11018


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 might be explained in such a scenario. 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 simplified phenomenological model for the dark matter density and temperature near the Earth, and confront this model with the new DAMA/LIBRA phase 2 data.
