DAMA observes an annual modulation in their event rate, as might be expected from dark matter scatterings, while CoGeNT has reported evidence for a similar modulation. The simplest interpretation of these findings in terms of dark matter-nucleus scatterings is excluded by other direct detection experiments. We consider the robustness of these exclusions with respect to assumptions regarding the scattering and find that isospin-violating inelastic dark matter helps alleviate this tension and… Expand

Can CoGeNT and DAMA Modulations Be Due to Dark Matter
We explore the dark matter interpretation of the anomalies claimed by the DAMA and cogent experiments, in conjunction with the various null direct-detection experiments. An independent analysis ofExpand

Recently the CRESST collaboration has published the long anticipated results of their direct Dark Matter (DM) detection experiment with a CaWO4 target. The number of observed events exceeds knownExpand
On the annual modulation signal in dark matter direct detection
We derive constraints on the annual modulation signal in Dark Matter (DM) direct detection experiments in terms of the unmodulated event rate. A general bound independent of the details of the DMExpand
Direct detection of dark matter in models with a light Z′
We discuss the direct detection signatures of dark matter interacting with nuclei via a new neutral gauge boson Z′, focussing on the case where both the dark matter and the Z′ have mass of a few GeV.Expand
Evidence for dark matter modulation in CoGeNT
We investigate the question of whether the recent modulation signal claimed by CoGeNT is best explained by the dark matter (DM) hypothesis from a Bayesian model comparison perspective. We considerExpand

Implications of the latest XENON100 and cosmic ray antiproton data for isospin-violating dark matter
In the scenario of isospin-violating dark matter (IVDM), the dark matter (DM) spin-independent couplings to protons and to neutrons are allowed to be different, which has been considered to relax theExpand


Consistent dark matter interpretation for CoGeNT and DAMA/LIBRA
In this paper, we study the recent excess of low-energy events observed by the CoGeNT Collaboration and the annual modulation reported by the DAMA/LIBRA Collaboration, and discuss whether theseExpand
CoGeNT Interpretations
Recently, the CoGeNT experiment has reported events in excess of expected background. We analyze dark matter scenarios which can potentially explain this signal. Under the standard case of spinExpand
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 rateExpand
Inelastic dark matter, non-standard halos and the DAMA/LIBRA results
The DAMA collaboration have claimed to detect particle dark matter (DM) via an annual modulation in their observed recoil event rate. This appears to be in strong disagreement with the null resultsExpand
