非相对论性暗物质（DM）可以通过散射高能宇宙射线（CR）电子来加速。这一过程导致相对论或半相对论DM的亚群，从而扩展了在亚GeV质量区直接探测的实验范围。在本文中，我们研究了这种机制的约束模型的光暗物质的当前和未来的潜力。特别是，我们发现超级神冈和XENON 1 T数据已经可以提供对暗物质通量的领先约束，这些暗物质已从宇宙射线电子加速到高能量。我们还研究了未来预计的敏感度DUNE和Hyper-K，并与以前的研究结果相反，得出的结论是，DUNE将能够取代超K界限的宇宙射线上散射DM的各种DM模型。
Nonrelativistic dark matter (DM) can be accelerated by scattering on high-energy cosmic-ray (CR) electrons. This process leads to a subpopulation of relativistic or semirelativistic DM which extends the experimental reach for direct detection in the sub-GeV mass regime. In this paper we examine the current and future potential of this mechanism for constraining models of light dark matter. In particular, we find that Super-Kamiokande and XENON1T data can already provide leading constraints on the flux of dark matter that has been accelerated to high energies from cosmic ray electrons. We also examine future projected sensitivities for DUNE and Hyper-K, and contrary to previous findings, conclude that DUNE will be able supersede Super-K bounds on cosmic-ray upscattered DM for a variety of DM models.
