作为μ子暗物质探测器的μ子g-2和EDM实验

Muon g-2 and EDM experiments as muonic dark matter detectors

Ryan Janish, Harikrishnan Ramani

摘要:

通过与核子、电子和光子的相互作用来探测超轻暗物质已经得到了深入的探索。在这项工作中,我们建议使用精确的μ介子实验,特别是μ介子g-2和电偶极矩测量,以检测超轻暗物质,主要耦合到μ介子。我们设置直接的,地面上的限制DM μ子的相互作用,使用现有的g-2数据,并表明,一个时间分辨的重新分析正在进行的和即将到来的岁差实验将是敏感的暗物质信号。有趣的是,我们还发现,目前的μ子g-2的异常可以解释为自旋力矩施加到μ子从一个赝标量暗物质的背景,诱导振荡的电偶极矩的μ子。这一解释可以通过时间分辨再分析来验证。

英文摘要:

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.
