研究了一个基于轻子味对称性的可重整化标量单重态暗物质模型。引入亲A标量偶线作为暗物质和标准模型粒子之间的中介。由于标量介质的味非对角相互作用，在满足当前各种实验和观测对暗物质的严格约束的同时，很容易保持所观察到的暗物质的遗迹丰度。我们进一步探讨了通过单圈过程直接探测暗物质的可能性。我们还发现，亲标量介体可以同时解释暗物质的残余丰度和μ子反常磁矩的差异。
We study a renormalizable scalar singlet dark matter model based onlepton flavor symmetry. A-philic scalar doublet is introduced as 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 further explore the possibility of dark matter direct detection through the one-loop process. We also find that the relic abundance of the dark matter and the discrepancy of the muon anomalous magnetic moment can be explained by the-philic scalar mediator simultaneously.
