论文摘要
暗物质(DM) - 电子散射是许多直接DM检测实验的主要目标,并且构成了探索DM在子GEV群众中的相互作用的有前途的途径,这挑战用核后退探测。我们扩展了最近提出的DM电子散射的晕晕分析方法,该方法允许推断局部DM光晕性能而没有任何其他假设,以通过目标材料的介电函数包括中等效应。我们表明,中等效应可能会显着影响葡萄球菌和硅的光环独立分析响应函数,因此对于从直接DM检测数据中正确推断局部DM光晕特性至关重要。
Dark matter (DM)-electron scattering is a prime target of a number of direct DM detection experiments and constitutes a promising avenue for exploring interactions of DM in the sub-GeV mass-range, challenging to probe with nuclear recoils. We extend the recently proposed halo-independent analysis method for DM-electron scattering, which allows to infer the local DM halo properties without any additional assumptions about them, to include in-medium effects through dielectric functions of the target material. We show that in-medium effects could significantly affect halo-independent analysis response functions for germanium and silicon and thus are essential for proper inference of local DM halo characteristics from direct DM detection data.
