Inelastic Dark Matter ∗
Many observations suggest that much of the matter of the universe is nonbaryonic. Recently, the DAMA NaI dark matter direct detection experiment reported an annual modulation in their event rate consistent with a WIMP relic. However, the Cryogenic Dark Matter Search (CDMS) Ge experiment excludes most of the region preferred by DAMA. We demonstrate that if the dark matter can only scatter by mak...
متن کاملHalo-independent methods for inelastic dark matter scattering
We present halo-independent methods to analyze the results of dark matter direct detection experiments assuming inelastic scattering. We focus on the annual modulation signal reported by DAMA/LIBRA and present three different halo-independent tests. First, we compare it to the upper limit on the unmodulated rate from XENON100 using (a) the trivial requirement that the amplitude of the annual mo...
متن کاملDeeply Inelastic Dark Matter: Beam Dumps as Wimp Cannons
We consider a phenomenological approach to constraining dark matter interactions with quarks by the exchange of a light mediator particle. We find that, for low WIMP masses, an old beam dump experiment provides stronger bounds than currently obtainable at the LHC with monojet searches. 1 A toy model for light dark matter The search for particle dark matter (DM) benefits from many and diverse ap...

متن کاملInelastic Dark Matter at DAMA, CDMS and Future Experiments
The DAMA annual modulation signature, interpreted as evidence for a spin-independent WIMP coupling, seems in conflict with null results from CDMS. However, in models of “inelastic dark matter”, the experiments are compatible. Inelastic dark matter can arise in supersymmetric theories as the real component of a sneutrino mixed with a singlet scalar. In contrast with ordinary sneutrino dark matte...
