论文摘要
我们提出了一种使用太阳中微子来加快暗物质的新型机制，灵感来自中微子是来自太阳中最有活力的颗粒，具有良好的光谱。在中微子门户的黑暗扇区模型中，我们表明，$ pp $ netrinos可以加速带有子gev质量的暗物质到速度高于$ 10^{ - 3} c $，并且能够在直接检测实验中沉积足够大的能量。这种机制的关键要素是自然界中存在的稳定暗物质结合状态的解离。所得的暗物质速度分布与太阳中微子光谱具有很强的形状。作为应用程序，我们通过重新解释了最近的PICO实验结果来得出对轻型暗物质相互作用的领先限制。
We present a novel mechanism of using solar neutrinos to speed up dark matter, inspired by the fact that neutrinos are the most energetic particles from the Sun with a well-understood spectrum. In a neutrino portal dark sector model, we show that dark matter with sub-GeV mass could be accelerated by the $pp$ neutrinos to velocities well above $10^{-3}c$ and capable of depositing large enough energy at direct detection experiments. A crucial ingredient of this mechanism is the dissociation of stable dark matter bound states that exist in Nature. The resulting dark matter velocity distribution bears a strong resemblance in shape to the solar neutrino spectrum. As an application, we derive a leading limit on light dark matter interaction by reinterpreting a recent PICO experiment result.
