摘要

更新之前的分析，我们使用弹性核反冲，我们研究了米格达尔效应，将描述WIMP与夸克和胶子相互作用的相对论有效场论的直接探测边界扩展到低WIMP质量，直到7维。为此，我们在分析中纳入了XENON1T、SuperCDMS、COSINE-100和DarkSide-50实验的数据，并假设了WIMP速度分布的标准麦克斯韦公式。我们发现，在高维算子的情况下，约束的能量尺度可能与有效理论的有效性不一致，但边界可以达到一个WIMP质量≃20 MeV。

Low-mass extension of direct detection bounds on WIMP-quark and WIMP-gluon effective interactions using the Migdal effect

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 $≃$ 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.
