We present two examples of velocity distributions for light dark matter particles that reconcile the annual modulation signal observed by DAMA with all other negative results from dark matter searches. They are: (1) a conventional Maxwellian distribution for particle masses around 5 to 9 GeV; (2) a dark matter stream coming from the general direction of Galactic rotation (not the Sagittarius stream). Our idea is based on attributing the DAMA signal to scattering off Na, instead of I, and can be tested in the immediate future by detectors using light nuclei, such as CDMS-II (using Si) and CRESST-II (using O).

The statement that this DAMA result is completely excluded by the results of these cryogenic experiments and is inconsistent with the SUSY interpretation (see, for example, [ref] ) is simply wrong (see also discussions in [ref] ).

This model-independent study of elastic scattering in Ref. [ref] is no longer applicable, as several new results have appeared recently.

Light dark matter no longer works in its original incarnation [ref] , but instead relies upon “channeling,” [ref] , a difficult to quantify effect whereby some fraction of nuclear recoils have essentially all of the energy converted into scintillation light, rather than just a fraction.

Yet this narrow mass region is in itself already significant, as dark matter in this mass range could potentially explain the hints seen at the DAMA experiment [ref] (though see also [ref] ).

Several alternative explanations of the DAMA signal have been proposed, such as the elastic scattering of light WIMPs (with mass $∼$ 7 GeV) [ref] , and very light candidates (e.g. with mass in the keV range) scattering off electrons [ref] .

Prior to the DAMA/LIBRA data, Ref. [ref] emphasized the low mass range 5–9 GeV; Ref. [ref] emphasized spin-dependent interactions; Ref. [ref] studies deviations from the standard halo assumptions; Ref. [ref] examined nonstandard velocity distributions (dark matter streams); Ref. [ref] proposed inelastic WIMP/nucleon scattering.
