Description
One of the most important signatures of dark matter in direct detection is
the annual modulation of the signal, due to the motion of the Earth around
the Sun. In inelastic scattering, the minimum velocity a WIMP must have to
deposit a recoil energy at the threshold of the detector is already close
to the galactic escape velocity. In this case the experiment probes the
tails of the dark matter halo velocity distribution where halo
substructures are expected. I will present halo-independent methods to
analyze the results of direct dark matter detection experiments assuming
inelastic scattering. I will specifically discuss the consistency of the
inelastic scattering interpretation of the DAMA annual modulation signal,
focusing on the tension with the bound from XENON100.
