Abstract

We explore extensions of inelastic Dark Matter and Magnetic inelastic Dark Matter where the WIMP can scatter to a tower of heavier states. We assume a WIMP mass mχO(1100)m_\chi \sim \mathcal{O}(1-100) GeV and a constant splitting between successive states δO(1100)\delta \sim\mathcal{O}(1 - 100) keV. For the spin-independent scattering scenario we find that the direct experiments CDMS and XENON strongly constrain most of the DAMA/LIBRA preferred parameter space, while for WIMPs that interact with nuclei via their magnetic moment a region of parameter space corresponding to mχ11m_{\chi}\sim 11 GeV and δ<15\delta < 15 keV is allowed by all the present direct detection constraints.
