Abstract

Self-interacting dark matter (SIDM) has been proposed to explain a number of observations on the galactic scale and smaller that are in conflict with collisionless dark matter simulations. We consider a model in which a small fraction of the SIDM consists of Strongly Interacting Massive Particles (SIMPs) that have strong interactions with baryons as well as with the SIDM particles. We show that the DAMA annual modulation signal can be caused by SIDM particles interacting with SIMPs trapped in iodine nuclei in the NaI detectors.
