论文摘要
我们将不同类型的存储环视为轴介导的单极偶极力的精确探针。我们表明，目前和计划的实验旨在非常精确地测量质子，muons和电子的磁性和电偶极矩，可能会探索除现有实验室界限以外的参数空间的新部分，并且在某些情况下，除了天体物理限制之外。值得注意的是，与Muons结合的光轴可能解释了fnal/bnl $（g-2）_μ$异常作为环境效应 - 地球核所产生的相干轴突场会促进穆恩（Muon）异常进度频率的额外贡献，该频率解释了对SM差异的差异。
We consider different types of storage rings as precision probes of axion-mediated monopole-dipole forces. We show that current and planned experiments aiming to measure magnetic and electric dipole moments of protons, muons and electrons very precisely may explore new parts of the parameter space beyond existing laboratory bounds and, in some cases, beyond astrophysical constraints. Remarkably, a light axion coupled to muons may explain the FNAL/BNL $(g-2)_μ$ anomaly as an environmental effect -- the coherent axion field generated by the earth nucleons induces an extra contribution to the anomalous precession frequency of the muon explaining the discrepancy with respect to the SM prediction.
