如果暗物质粒子带电荷,就像在带电暗物质模型中那样,这些粒子应该在产生普通宇宙射线的天体物理加速器中被加速,它们的光谱应该具有可预测的刚性依赖关系。根据电荷的不同,由此产生的“暗宇宙射线”可以在超级神冈探测器、冰立方探测器和其他探测器中被探测到类似μ子或中微子的事件。我们提出了新的限制,并提出了一些新的分析,特别是对于超级神冈实验,它可以探测以前未探索的带电暗物质参数空间的一部分。我们的大多数结果都是相当普遍的,适用于广泛的暗物质模型。
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.
