暗宇宙射线

Dark Cosmic Rays

Ping-Kai Hu, Alexander Kusenko, Volodymyr Takhistov

摘要:

如果暗物质粒子带有电荷,就像在毫荷电暗物质模型中一样,那么这些粒子应该在产生普通宇宙射线的相同天体物理加速器中加速,它们的光谱应该具有可预测的刚性依赖性。根据电荷的不同,所产生的“暗宇宙射线“可以在超级神冈、冰立方和其他探测器中被探测为类似μ介子或中微子的事件。我们提出了新的限制,并提出了几个新的分析,特别是,超级神冈实验,它可以探测以前未探索的部分millicharged暗物质参数空间。我们的大多数结果是相当普遍的,适用于广泛的一类暗物质模型。

英文摘要:

If dark matter particles have an electric charge, as in models of millicharged dark matter, such particles should be accelerated in the same astrophysical accelerators that produce ordinary cosmic rays, and their spectra should have a predictable rigidity dependence. Depending on the charge, the resulting "dark cosmic rays" can be detected as muon-like or neutrino-like events in Super-Kamiokande, IceCube, and other detectors. We present new limits and propose several new analyses, in particular, for the Super-Kamiokande experiment, which can probe a previously unexplored portion of the millicharged dark matter parameter space. Most of our results are fairly general and apply to a broad class of dark matter models.
