Figure 1: Simplified plot showing the predicted WIMP-nucleon scattering cross section as a function of WIMP mass. Asymmetric dark matter models (light blue area) predict WIMPs with masses of a few GeV/c2; generic WIMP models (dark blue area) predict larger masses of hundreds of GeV/c2 or more. Parts of these parameter regions have been probed and excluded by current experiments (red area). The signal excess of the CDMS experiment points towards relatively light WIMPs (green area). However, the absence of a signal in the LUX experiment is in tension with this result. Most of the expected parameter space could be probed in the near future, until a background from coherent neutrino-nucleus scattering (yellow area) becomes relevant, interfering with possible dark matter signals.
