论文摘要
通过电子回路测量值的异种XENON1T的过量，我们研究了在Lepton违规实验中探测轴突样颗粒（ALP）的前景。特别是，我们将这种ALP视为伪金石，这是通过自发破裂的风味对称性解释的，这些味道对称性解释了标准模型leptons的混合结构。我们介绍了风味对称性是非亚伯u（2）和源自其u（1）亚组的ALP，该亚组无异常，与标准模型组无异常。我们构建了两个明确的现实示例，这些例子重现了麻血质量和混合，并表明与Xenon1T异常一致的ALP可以通过提出的LFV实验来探测。
Motivated by the Xenon1T excess in electron-recoil measurements, we investigate the prospects of probing axion-like particles (ALP) in lepton flavor violation experiments. In particular, we identify such ALP as a pseudo-Goldstone from the spontaneous breaking of the flavor symmetries that explain the mixing structure of the Standard Model leptons. We present the case of the flavor symmetries being a non-Abelian U(2) and the ALP originating from its U(1) subgroup, which is anomaly-free with the Standard Model group. We build two explicit realistic examples that reproduce leptonic masses and mixings and show that the ALP which is consistent with Xenon1T anomaly could be probed by the proposed LFV experiments.
