摘要

我们给出了轴子的完整Wess-Zumino-Witten相互作用的一致推导，包括保证标准模型规范不变性所必需的反项。通过将轴子场的导数作为背景规范场并加入辅助的手性旋转相，我们保证了轴子相互作用拉格朗日量的一致性。这种方法使我们能够推导出轴子与规范玻色子和矢量介子之间与基无关的物理相互作用。这些相互作用在轻、重轴子粒子的轴子现象学中有广泛的应用。2025年由美国物理学会出版

Wess-Zumino-Witten Interactions of Axions

We present a consistent derivation of the complete Wess-Zumino-Witten interactions of axions, including the counter-term necessary to guarantee the gauge invariance of the standard model. By treating the derivative of the axion field as a background gauge field and incorporating auxiliary chiral rotation phases, we ensure consistency in the axion-interaction Lagrangian. This approach allows us to derive basis-independent physical interactions of axions with gauge bosons and vector mesons. These interactions have broad applications in axion phenomenology for both light and heavy axion particles.
