论文摘要
我们表明，与文献中的主张相反，对轴突 - 光子耦合的主要贡献不必以与$ e^2 $成比例的单位进行量化。特别是，我们讨论了此量化的论点中的一个漏洞，然后提供明确的反例。因此，我们构建了一个通用的轴突 - 光子有效的Lagrangian，并发现轴突 - 光子耦合可能以先前未知的Wilson系数为主。我们表明，该结果意味着对常规轴心电动力学的重大修饰，并为轴支实验设定了新目标。我们的理论分析的核心是对轴和磁性单翼之间相互作用的批判性重新审查。我们表明，与文献中的主张相反，磁性单极不必给轴质量。此外，我们发现将来检测具有某些参数的轴或轴状粒子可以作为磁性物质存在的证据。
We show that, contrary to assertions in the literature, the main contribution to the axion-photon coupling need not be quantized in the units proportional to $e^2$. In particular, we discuss a loophole in the argument for this quantization and then provide explicit counterexamples. Hence, we construct a generic axion-photon effective Lagrangian and find that the axion-photon coupling may be dominated by previously unknown Wilson coefficients. We show that this result implies a significant modification of conventional axion electrodynamics and sets new targets for axion experiments. At the core of our theoretical analysis lies a critical reexamination of the interactions between axions and magnetic monopoles. We show that, contrary to claims in the literature, magnetic monopoles need not give mass to axions. Moreover, we find that a future detection of an axion or axion-like particle with certain parameters can serve as evidence for the existence of magnetically charged matter.
