Mentions: There is a large number of recent results reported by experiments using crystals [1101, 1102], semiconductors [1103, 1104] and noble gases [1099, 1105] as sensitive material. The excess of events reported by some of these experiments [1101, 1102, 1104, 1106], which would appear to point to a very light WIMP, are confronted by the stringent limits set by negative results in the searches by the xenon-based detectors, Xenon-100 [1107] and LUX [1099]. These limits are cutting into the region of scattering cross sections typical of the MSSM (see Fig. 124) and therefore provide some meaningful bounds, even if the systematics and model dependencies due to the assumed DM profile in the galaxy are known to be sizeable [1108]. In particular, the Xenon-100 and LUX bounds – if taken at face value – exclude a sizeable fraction of the viable SUSY points with neutralino DM at small values of the and parameters, which would give chargino- and neutralino-pair production observables at a linear collider with below 1 TeV and small fine tuning, as discussed above. In the case where WIMPs make up only a portion of the total DM abundance (perhaps the bulk is composed of axions), these direct detection predictions would have to be rescaled by a factor , in which case the search limits are much less constraining.Fig. 124
