论文摘要

通过与相对论电子和质子在Blazar射流中加速弹性相撞后,大黄蜂中心附近的暗物质颗粒可以充满活力,足以触发陆地探测器的可检测信号。在这项工作中,专注于Blazars TXS 0506+056和Bl lacertae,我们通过可用的Super-Kamiokande数据来得出了暗物质和电子之间弹性散射的横截面的新限制。得益于大型Blazar增强的暗物质通量,深色物质质量的暗物质 - 电子散射横截面的极限可能低至$ \ sim10^{ - 38}〜\ text {cm}^2 $,这是比银色COSMIC COSMIC RAYS的类似结果。

Dark matter particles near the center of a blazar, after being accelerated by the elastic collisions with relativistic electrons and protons in the blazar jet, can be energetic enough to trigger detectable signals at terrestrial detectors. In this work, focusing on the blazars TXS 0506+056 and BL Lacertae, we derive novel limits on the cross section of the elastic scattering between dark matter and electrons by means of the available Super-Kamiokande data. Thanks to the large blazar-boosted dark matter flux, the limit on the dark matter-electron scattering cross section for dark matter masses below 100 MeV can be as low as $\sim10^{-38}~\text{cm}^2$, which is orders of magnitude stronger than the analogous results from galactic cosmic rays.
