随着暗物质搜索进入亚GeV质量范围，他们寻找通过与暗粒子直接散射而电离的电子。然而，暗物质从原子核散射也可以通过米格达尔效应产生电子。在本文中，作者表明，Migdal效应可以显着贡献的信号速率，并已被包括在解释实验结果时。
As dark matter searches push into the sub-GeV mass range, they look for electrons ionized by direct scattering with dark particles. However, dark matter scattering off nuclei can also produce electrons through the Migdal effect. In this paper the authors show that the Migdal effect can contribute significantly to signal rates and has to be included when interpreting experimental results.
