论文摘要
Leptoquark（LQ）模型是$（G-2）_μ$异常的动机解决方案。在最小的LQ模型中，只有特定的表示可以导致手性增强。对于标量LQS，$ R_2 $和$ S_1 $可以导致顶级夸克性手性增强功能。对于向量LQS，$ v_2 $和$ u_1 $可以导致底部的夸克性手性增强功能。当我们同时考虑LQ和类似矢量的夸克（VLQ）时，可能会有更多场景。在我们以前的工作中，我们考虑了具有上类型夸克手性增强的标量LQ和VLQ扩展模型。在这里，我们研究了标量LQ和VLQ扩展模型，具有颜色类型的夸克性手性增强。我们发现了两个新型号，$ b $ Quark手性增强功能，它们源自底部和底部伴侣的混合。然后，我们在$（g-2）_ $的约束下提出了新的LQ和VLQ搜索渠道。
Leptoquark (LQ) models are well motivated solutions to the $(g-2)_μ$ anomaly. In the minimal LQ models, only specific representations can lead to the chiral enhancements. For the scalar LQs, the $R_2$ and $S_1$ can lead to the top quark chiral enhancement. For the vector LQs, the $V_2$ and $U_1$ can lead to the bottom quark chiral enhancement. When we consider the LQ and vector-like quark (VLQ) simultaneously, there can be more scenarios. In our previous work, we considered the scalar LQ and VLQ extended models with up-type quark chiral enhancement. Here, we study the scalar LQ and VLQ extended models with down-type quark chiral enhancement. We find two new models with $B$ quark chiral enhancement, which originate from the bottom and bottom partner mixing. Then, we propose new LQ and VLQ search channels under the constraints of $(g-2)_μ$.
