The authors' main claim We show that a population of relic neutralinos, which was already proved to fit the DAMA/LIBRA data on the annual modulation effect, could naturally explain the two candidate CDMS II events, if these are actually due to a dark matter signal.

The CDMS Collaboration has presented its results for the final exposure of the CDMS II experiment and reports that two candidate events for dark matter would survive after application of the various discrimination and subtraction procedures inherent in their analysis. We show that a population of relic neutralinos, which was already proved to fit the DAMA/LIBRA data on the annual modulation effect, could naturally explain the two candidate CDMS II events, if these are actually due to a dark matter signal.

The paper
Original abstract
The CDMS Collaboration has presented its results for the final exposure of the CDMS II experiment and reports that two candidate events for dark matter would survive after application of the various discrimination and subtraction procedures inherent in their analysis. We show that a population of relic neutralinos, which was already proved to fit the DAMA/LIBRA data on the annual modulation effect, could naturally explain the two candidate CDMS II events, if these are actually due to a dark matter signal.

The DAMA/LIBRA signal corresponds a DM cross-section/nucleon of order $10^-39$ cm$^2$, at a WIMP mass of 5 GeV [ref] with a signal band that extends roughly linearly down to 5-42 cm$^2$ at a mass of 50 GeV [ref] .

In particular, the XENON upper bound [ref] suffers from large uncertaities due to conflicting determinations of the scintillation efficiency at low nuclear recoils (as shown in Fig. 12 of [ref] ). �Calculations performed in Ref. [ref] (though with a threshold energy somewhat smaller than the one of XENON10) indicate that at a WIMP mass of order 10 GeV the bound of Ref. [ref] should be relaxed by more than an order of magnitude.

In the case of Fig. [ref], the contours refer to 68% and 85% C.L., and they evolve into an open region (i.e. into an upper bound) at the 90% C.L., a result compatible to the one obtained in Ref. [ref] , where a slightly different statistical analysis is adopted.
