Description
We explore a scenario in which Magnetic inelastic Dark Matter can scatter to a tower of heavier states.The splitting between successive states is assumed to be a constant $\delta \sim\mathcal{O}$(keV). Such a spectrum with small mass splittings can arise naturally in an extradimensional model with a large compactification radius. We find that a region of parameter space corresponding to $m_{\chi}\sim14$ GeV and $\delta < 20$ keV is allowed by the constraints from XENON100, KIMS, CDMS, CRESST II and ZEPLIN III.
