论文摘要
更新了先前的分析，我们使用弹性核后坐力我们研究了Migdal效应，以扩展到低WIMP质量，直接将直接检测范围延伸到操作员，直到描述了与夸克和胶子相互作用的相对论有效野外理论的维度7。为此，我们在分析中包括Xenon1t，SuperCDM，Cosine-100和Darkside-50实验的数据，并假设WIMP速度分布的标准Maxwellian。我们发现，界限可以达到WIMP质量$ \ simeq $ 20 MEV，尽管在高维操作员的情况下，随后的约束的能量尺度可能与有效理论的有效性不一致。
Updating a previous analysis where we used elastic nuclear recoils we study the Migdal effect to extend to low WIMP masses the direct detection bounds to operators up to dimension 7 of the relativistic effective field theory describing WIMP interactions with quarks and gluons. To this aim we include in our analysis the data of the XENON1T, SuperCDMS, COSINE-100, and DarkSide-50 experiments and assume a standard Maxwellian for the WIMP velocity distribution. We find that the bounds can reach down to a WIMP mass $\simeq$20 MeV, although in the case of higher-dimension operators the energy scale of the ensuing constraints may be inconsistent with the validity of the effective theory.
