Abstract

Weakly Interacting Massive Particles (WIMPs) may constitute most of the matter in the Universe. There are intriguing results from DAMA/LIBRA, CoGeNT and CRESSTII, and more recently CDMS-Si suggesting a relatively light dark matter candidate of mass <10 GeV/c2. At the same time, experiments using heavy nuclear targets such as CDMS-Ge and XENON detectors suggest that there is no DM candidates with MW > 15 GeV/c2. We review the existing experiments and the problems associated with light mass WIMP detection. We find that all six experiments considered (DAMA, CoGeNT, CRESST, CDMS-Si, CDMS-Ge, XENON) are consistent if one assumes that the mass of WIMP is lower than expected: 3.4 < MW < 6.8 GeV/c2. This is followed by a discussion of the properties of "new" detectors, which may enable more reliable detection of low mass WIMPs.
