论文摘要
我们研究了直接检测来自具有高能宇宙颗粒（例如质子和电子）的散射产生的增强的暗物质的可能性。作为一个具体的例子，我们考虑由标准模型中与$ u（1）_y $ gauge-Boson混合的$ u（1）_d $ gauge Boson介导的子GEV暗物质。在与宇宙射线碰撞相撞的光线暗物质的增强动能可以在地下直接检测实验中反冲目标核和电子，从而将足够的能量转移到它们以可检测到它们。我们通过现有的直接检测实验以及对撞机和横梁降低实验显示了BDM的影响。
We study the possibility to directly detect the boosted dark matter generated from the scatterings with high energetic cosmic particles such as protons and electrons. As a concrete example, we consider the sub-GeV dark matter mediated by a $U(1)_D$ gauge boson which has mixing with $U(1)_Y$ gauge boson in the standard model. The enhanced kinetic energy of the light dark matter from the collision with the cosmic rays can recoil the target nucleus and electron in the underground direct detection experiments transferring enough energy to them to be detectable. We show the impact of BDM with existing direct detection experiments as well as collider and beam-dump experiments.
