论文摘要
我们讨论了两种模型，这些模型是$ b \ to s l^+ l^ - $ n- $衰减，暗物质（DM）问题和MUON $（G-2）$异常的违反Lepton风味普遍性的共同说明。 $ b $梅森的衰变和MUON $（G-2）$异常，用带有DM候选人的额外的单循环图来解释。相对于标准模型（SM），这些模型具有一个额外的费米字段和两个额外的标量字段。 $ su（3）$量子数是通过与新的Yukawa Lagrangian中的SM Fermions的交互来固定的，该Yukawa Lagrangian连接了黑暗和可见扇区。我们比较了两个模型，其中一种模型为单元，标量为$ su（2）_l $，而另一一种是fermion是Doublet，而标量为$ su（2）_l $的单元。我们得出的结论是，这两个模型都可以同时解释所有新物理现象，同时满足所有其他风味和DM约束。但是，DM约束如何影响两个模型导致允许的DM质量范围明显差异之间存在至关重要的差异。
We discuss two models which are part of a class providing a common explanation for lepton flavor universality violation in $b \to s l^+ l^- $ decays, the dark matter (DM) problem and the muon $(g-2)$ anomaly. The $B$ meson decays and the muon $(g-2)$ anomalies are explained by additional one-loop diagrams with DM candidates. The models have one extra fermion field and two extra scalar fields relative to the Standard Model (SM). The $SU(3)$ quantum numbers are fixed by the interaction with the SM fermions in a new Yukawa Lagrangian that connects the dark and the visible sectors. We compare two models, one where the fermion is a singlet and the scalars are doublets under $SU(2)_L$ and another one where the fermion is a doublet and the scalars are singlets under $SU(2)_L$. We conclude that both models can explain all new physics phenomena simultaneously, while satisfying all other flavor and DM constraints. However, there are crucial differences between how the DM constraints affect the two models leading to a noticeable difference in the allowed DM mass range.
