论文摘要
我们重新审视了与叶子相互作用的轴突样颗粒（ALP）的理论和约束。我们在ALP参数空间的约束中阐明了一些微妙之处，并找到了一些新的ALP检测机会。我们确定了弱侵入性和弱化的阿尔卑斯山之间的质量差异，由于在各种过程中可能的“能量增强”，它们会极大地改变当前限制。这种新的理解会通过充满电的梅森腐烂（例如$π^+ \ to e^+νa$，$ k^+ \ to e^+νa$）和$ w $ boson衰减带来ALP检测的其他机会。新的边界会影响弱化和弱化的阿尔卑斯山，并对QCD轴轴承有影响，并使用阿尔卑斯山解决实验异常。
We revisit the theory and constraints on axion-like particles (ALPs) interacting with leptons. We clarify some subtleties in the constraints on ALP parameter space and find several new opportunities for ALP detection. We identify a qualitative difference between weak-violating and weak-preserving ALPs, which dramatically change the current constraints due to possible "energy enhancements" in various processes. This new understanding leads to additional opportunities for ALP detection through charged meson decays (e.g., $π^+\to e^+ νa$, $K^+\to e^+ νa$) and $ W $ boson decays. The new bounds impact both weak-preserving and weak-violating ALPs and have implications for the QCD axion and addressing experimental anomalies using ALPs.
