仇外暗物质

Xenophobic Dark Matter

Jonathan L. Feng, Jason Kumar, David Sanford

摘要:

我们认为模型的仇外暗物质,其中违反同位旋的暗物质-核子相互作用显着降低氙直接探测实验的响应。对于模型的近最大仇外心理,与中子-质子耦合比$f_n / f_p \approx -0.64$,和暗物质质量接近8 GeV,感兴趣的区域CoGeNT和CDMS-Si和CDMS-Ge数据中的Collar和Fields确定的感兴趣的区域可以达成一致。这个模型可能会在未来的直接,间接和对撞机搜索进行测试。有趣的是,由于氙的天然同位素丰度意味着仇外心理有其局限性,我们发现这种仇外心理模型可能会在不久的将来通过氙实验进行探索。LHC和费米-LAT在不久的将来的数据也可能提供有趣的替代探针的仇外暗物质。

英文摘要:

We consider models of xenophobic dark matter, in which isospin-violating dark matter-nucleon interactions significantly degrade the response of xenon direct detection experiments. For models of near-maximal xenophobia, with neutron-to-proton coupling ratio $f_n / f_p \approx -0.64$, and dark matter mass near 8 GeV, the regions of interest for CoGeNT and CDMS-Si and the region of interest identified by Collar and Fields in CDMS-Ge data can be brought into agreement. This model may be tested in future direct, indirect, and collider searches. Interestingly, because the natural isotope abundance of xenon implies that xenophobia has its limits, we find that this xenophobic model may be probed in the near future by xenon experiments. Near-future data from the LHC and Fermi-LAT may also provide interesting alternative probes of xenophobic dark matter.
