Can the DAMA/LIBRA Annual Modulation Signal be Explained by Dark Matter?

T. Schwetz

I give a brief summary on the status of Dark Matter (DM) explanations of the annual modulation signal observed in DAMA/LIBRA. I stress that for spin-independent elastic scattering the issue of ion channeling is crucial. While in the presence of channeling a marginal compatibility is obtained between DAMA and other constraints, the DM interpretation is strongly disfavoured without channeling. A similar situation –- though slightly less conclusive –- applies also in the cases of spin-dependent and inelastic DM scattering.
