Abstract
We perform a global fit to data from Dark Matter (DM)direct detection experiments, including the recent CDMS-II results. Wediscuss possible interpretations of the DAMA annual modulation signalin terms of spin-independent and spin-dependent DM-nucleusinteractions, both for elastic and inelastic scattering. We find thatfor the spin-dependent inelastic scattering off protons a good fit to alldata is obtained. We present a simple toy model realizing such a scenario.In all the remaining cases the DAMA allowed regions are disfavored by otherexperiments or suffer from severe fine tuning of DM parameters withrespect to the galactic escape velocity. Finally, we also entertain the possibility that the two events observed inCDMS-II are an actual signal of elastic DM scattering, and we compare theresulting CDMS-II allowed regions to the exclusion limits from otherexperiments.
