论文摘要
我们研究了基于$ z_4 $ Lepton风味对称性的可重新分配标量旋转暗物质模型。引入了$μτ$ - 湿的标量双线，以解释实验值与muon异常磁矩的理论预测之间的差异。同时，这些调味标量扮演着连接暗物质和标准模型颗粒的调解人的角色。由于标量介体的风味异性相互作用，从各种实验和观察结果满足了当前对暗物质的严重限制，因此很容易保持暗物质的遗物丰度。我们还通过一环过程探索了暗物质直接检测的可能性。
We study a renormalizable scalar singlet dark matter model based on $Z_4$ lepton flavor symmetry. A $μτ$-philic scalar doublet is introduced to explain the discrepancy between the experimental value and the theoretical prediction of the muon anomalous magnetic moment. At the same time, these flavored scalars play the role of a mediator which connects dark matter and standard model particles. The observed relic abundance of the dark matter is easily maintained while satisfying the current severe constraints on the dark matter from various experiments and observations thanks to the flavor off-diagonal interactions of scalar mediators. We also explore the possibility of dark matter direct detection through the one-loop process.
