Light Magnetic Dark Matter in Direct Detection Searches
  We study a fermionic Dark Matter particle carrying magnetic dipole moment and
analyze its impact on direct detection experiments. In particular we show that
it can accommodate the DAMA, CoGeNT and CRESST experimental results. Assuming
conservative bounds, this candidate is shown not to be ruled out by the CDMS,
XENON and PICASSO experiments. We offer an analytic understanding of how the
long-range interaction modifies the experimental allowed regions, in the cross
section versus Dark Matter mass parameter space, with respect to the typically
assumed contact interaction. Finally, in the context of a symmetric Dark Matter
sector, we determine the associated thermal relic density, and further provide
relevant constraints imposed by indirect searches and colliders.
