Magnetic Fluffy Dark Matter

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 $m_{\chi }\sim \mathcal{O}(1-100)$ GeV and a constant splitting between successive states $\delta \sim \mathcal{O}(1-100)$ 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 $m_{\chi }\sim 11$ GeV and $\delta <15$ keV is allowed by all the present direct detection constraints.
