论文摘要
通过与核子,电子和光子的相互作用来检测超轻暗物质。在这项工作中,我们建议使用精确的MUON实验,特别是MUON G-2和电动偶极矩测量,以检测主要与Muons结合的超轻暗物质。我们使用现有的G-2数据对DM-MUON相互作用进行了直接的陆地限制,并表明对正在进行的进动实验的时间分辨重新分析将对暗物质信号敏感。有趣的是,我们还发现,当前的MUON G-2异常可以通过施加到伪尺度暗物质背景的MUON的旋转扭矩来解释,该扭矩可诱导MUON振动的电偶极矩。该解释可以通过时间分辨的重新分析来验证。
The detection of ultralight dark matter through interactions with nucleons, electrons, and photons has been explored in depth. In this work we propose to use precision muon experiments, specifically muon g-2 and electric dipole moment measurements, to detect ultralight dark matter that couples predominantly to muons. We set direct, terrestrial limits on DM-muon interactions using existing g-2 data, and show that a time-resolved reanalysis of ongoing and upcoming precession experiments will be sensitive to dark matter signals. Intriguingly, we also find that the current muon g-2 anomaly can be explained by a spin torque applied to muons from a pseudoscalar dark matter background that induces an oscillating electric dipole moment for the muon. This explanation may be verified by a time-resolved reanalysis.
