The inelastic dark matter model, in which WIMP-nucleus scatterings occur via
transition to an excited WIMP state ~
100 keV above the ground state, modify the relative sensitivities of various dark
matter direct detection
experiments. In this model, the DAMA annual modulation signature can arise
consistent with presently null results
at CDMS-Soudan, XENON10, CRESST, and KIMS. The neutralino, in an R-
symmetric SUSY model, can provide a
natural example of such a model. We review the status of the relative
experiments and their sensitivities, and make
predictions for upcoming experiments. In particular, we note that the model
predicts highly suppressed signals at
low energy, with most nuclear recoil events typically occuring between 20 to 45
keV at xenon and iodine
experiments. |
