Interfering composite asymmetric dark matter as explanation for DAMA and CoGeNT results

Research output: Contribution to journalJournal articleResearchpeer-review

Abstract

We provide a simple mechanism for reconciling the direct dark matter experimental results. We consider light asymmetric composite dark matter which scatters off nuclei via Higgs and photon exchange. We demonstrate that the interference between these two channels naturally accommodates the experimental results. We discover that this happens for a compositeness scale of the order of the electroweak. We also provide a model realization based on strong dynamics at the electroweak scale.
