论文摘要
中性且长寿的$η$和$η'$ Mesons的衰败提供了一个独特的，具有风味的实验室，以测试低能量子染色体动力学，并在标准模型之外搜索新物理学。近年来，他们吸引了全球关注，并激发了不同高强度范围中心的广泛实验计划。新的实验数据将提供关键的输入，以精确确定光夸克质量比，$η$ - $η'$混合参数以及对MUON异常磁矩的耐药贡献。同时，它将提供一个敏感的探针来测试潜在的新物理学。这包括搜索隐藏的光子，光希格斯标量和类似轴突的颗粒，这些颗粒与全球范围内的努力互补，以检测到GEV质量尺度以下的新光颗粒以及离散对称性违规的测试。在这篇评论中，我们提供了有关理论发展的最新信息，讨论实验机会，并确定该领域所需的未来研究。
Decays of the neutral and long-lived $η$ and $η'$ mesons provide a unique, flavor-conserving laboratory to test low-energy Quantum Chromodynamics and search for new physics beyond the Standard Model. They have drawn world-wide attention in recent years and have inspired broad experimental programs in different high-intensity-frontier centers. New experimental data will offer critical inputs to precisely determine the light quark mass ratios, $η$-$η'$ mixing parameters, and hadronic contributions to the anomalous magnetic moment of the muon. At the same time, it will provide a sensitive probe to test potential new physics. This includes searches for hidden photons, light Higgs scalars, and axion-like particles that are complementary to worldwide efforts to detect new light particles below the GeV mass scale, as well as tests of discrete symmetry violation. In this review, we give an update on theoretical developments, discuss the experimental opportunities, and identify future research needed in this field.
