Abstract

We examine data from the DAMA, CoGeNT, CRESST-II and CDMS/Si direct detection experiments in the context of multicomponent hidden sector dark matter. The models considered feature a hidden sector with two or more stable particles charged under an unbroken U(1) gauge interaction. The new gauge field can interact with the standard U(1)Y via renormalizable kinetic mixing, leading to Rutherford-type elastic scattering of the dark matter particles off ordinary nuclei. We consider the simplest generic model of this type, with a hidden sector composed of two stable particles, F1 and F2. We find that this simple model can simultaneously explain the DAMA, CoGeNT, CRESST-II and CDMS/Si data. This explanation has some tension with the most recent results from the XENON100 experiment.
