论文摘要
在最近的Xenon1t结果的推动下，我们研究了嗜血型口味依赖性无异常的轴突样粒子（ALP）及其对带电的莱普顿风味违规（CLFV）的影响。我们提出了两个代表性模型。第一个认为，ALP起源于Flavon产生带电的莱普顿群众。第二个模型假定了更大的风味对称性，因此可以在带电的lepton中进行更一般的混合，同时保持依赖风味的ALP耦合。我们发现，解释Xenon1t结果的KEV ALP仍然可用于轻顿风味和恒星冷却天体物理极限。另一方面，如果确认了Xenon1t结果，则未来的CLFV测量值可以互补，以探测这种可能性。
Motivated by the recent Xenon1T result, we study a leptophilic flavour-dependent anomaly-free axion-like particle (ALP) and its effects on charged-lepton flavour violation (CLFV). We present two representative models. The first one considers that the ALP origins from the flavon that generates the charged-lepton masses. The second model assumes a larger flavour symmetry such that more general mixings in the charged-lepton are possible, while maintaining flavour-dependent ALP couplings. We find that a keV ALP explaining the Xenon1T result is still viable for lepton flavour violation and stellar cooling astrophysical limits. On the other hand, if the Xenon1T result is confirmed, future CLFV measurements can be complementary to probe such a possibility.
