论文摘要
我们研究了一类新的信号，其中费米子暗物质被绑定的电子靶标吸收。直接检测中的费莫原子吸收信号和中微子实验对暗物质质量敏感，并探测了一个参数空间区域，在该区域中，暗物质在这些区域中否则挑战性地检测到了。我们计算基于氙气检测器中的速率和能量沉积光谱，对当前和将来的实验进行了预测。我们提出了两个可能显示电子吸收的模型，并根据其他约束来研究检测前景。
We study a new class of signals where fermionic dark matter is absorbed by bound electron targets. Fermionic absorption signals in direct detection and neutrino experiments are sensitive to dark matter with sub-MeV mass, probing a region of parameter space in which dark matter is otherwise challenging to detect. We calculate the rate and energy deposition spectrum in xenon-based detectors, making projections for current and future experiments. We present two possible models that display fermionic absorption by electrons and study the detection prospects in light of other constraints.
