磁蓬松暗物质

Magnetic Fluffy Dark Matter

Kunal Kumar, Arjun Menon, Tim M. P. Tait

摘要:

我们探讨了非弹性暗物质和磁性非弹性暗物质的WIMP可以散射到一个塔的较重的状态。我们假设WIMP质量为$m_χ\sim \mathcal{O}(1-100)$ GeV,连续态$δ\sim\mathcal{O}(1 - 100)$ keV之间的分裂是恒定的。对于自旋无关散射的情况下,我们发现,直接实验CDMS和XENON强烈约束大多数的DAMA/LIBRA首选的参数空间,而对于WIMPs通过其磁矩与原子核相互作用的参数空间对应于$m_χ\sim 11 $ GeV和$δ< 15$ keV的区域是允许的所有目前的直接检测约束。

英文摘要:

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