最新的异常μ子磁矩的测量结果表明，标准模型的理论预测与实验观测之间存在差异。为了解释这种差异，我们考虑了一种可能的扩展类型-（I+II）的跷跷板模型的中微子质量产生与规范对称性。通过明确地构建一个只有一个额外标量单态的经济模型，我们证明了规范对称性及其自发破缺不仅对解释μ子结果至关重要，而且对产生中微子质量和轻子味混合也至关重要。各种唯象的影响和实验的模型参数的限制进行了讨论。
The latest measurements of the anomalous muon magnetic moment show a discrepancy between the theoretical prediction of the Standard Model and the experimental observations. To account for such a discrepancy, we consider a possible extension of the type-(I+II) seesaw model for neutrino mass generation with a gauged symmetry. By explicitly constructing an economical model with only one extra scalar singlet, we demonstrate that the gauge symmetry and its spontaneous breaking are crucial not only for explaining the muon result but also for generating the neutrino masses and leptonic flavor mixing. Various phenomenological implications and experimental constraints on the model parameters are also discussed.
