论文摘要
深色核散射中的migdal效应通过电子离子化，将直接搜索实验扩展到亚gev质量区域，并具有子键检测阈值。在本文中，我们得出了一个严格且与模型无关的“ Migdal-Photoabssorptict”关系，该关系将子键Migdal过程与光吸附联系起来。这种关系不含理论不确定性，因为它仅需要光吸附横截面作为实验输入。在Xenon的情况下，该关系的有效性通过实验良好的基准标准化了XENON的情况。提出和讨论了基于此Xenon，Argon，Semiconductor硅和锗检测器的预测。
The Migdal effect in a dark-matter-nucleus scattering extends the direct search experiments to the sub-GeV mass region through electron ionization with sub-keV detection thresholds. In this paper, we derive a rigorous and model-independent "Migdal-photoabsorption" relation that links the sub-keV Migdal process to photoabsorption. This relation is free of theoretical uncertainties as it only requires the photoabsorption cross section as the experimental input. Validity of this relation is explicitly checked in the case of xenon with an state-of-the-arts atomic calculation that is well-benchmarked by experiments. The predictions based on this relation for xenon, argon, semiconductor silicon and germanium detectors are presented and discussed.
