论文摘要
有两个来源有助于解释$ \ text {r} _ \ text {k} $，$ \ text {r} _ {\ text {k}^*} $ Anomalies在MF331模型中。第一个是新的中性量规玻色子$ \ text {z}^{\ prime} $的非lfuv耦合，$ \ text {g}^{g}^{\ text {z}^\ prime}^\ prime}（e） $ \ text {r} _ \ text {k} $，$ \ text {r} _ {\ text {k}^*} $ anmalies通过$ \ text {z}^\ prime $ -penguin图，涉及新的充电bosons $ \ pmosons $ \ text text $ \ pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pm pmpm}盒子图的贡献是第二个来源，它仅诱导了第一代。我们表明，企鹅图无法解释$ \ text {r} _ \ text {k} $，$ \ text {r} _ {\ text {k}^*} $异常，并且需要框图。 $ \ text {r} _ \ text {k} $和$ \ text {r} _ {\ text {k}^*} $的实验约束{k} $和$ \ text {r} _ {\ text {k}^*} $导致新的粒子质量变性。 NP对分支比率的贡献$ \ text {br}（\ text {b} \toμ^+μ^ - ），\ text {br}（\ text {b} \ ssγ）$预测结果与NP量表允许的区域的实验限制一致。
There are two sources that help to explain the $\text{R}_\text{K}$, $\text{R}_{\text{K}^*}$ anomalies in the MF331 model. The first is non-LFUV couplings of the new neutral gauge boson $\text{Z}^{\prime}$ with leptons, $\text{g}^{\text{Z}^\prime}(e)\neq \text{g}^{\text{Z}^\prime}(μ,τ)$, which causes the $\text{R}_\text{K}$, $\text{R}_{\text{K}^*}$ anomalies via $\text{Z}^\prime$-penguin diagrams involving newly charged gauge bosons $\text{X}^{\pm}_μ$, and exotic U-quarks. The box diagram's contribution is the second source, which induced only the first lepton generation. We show that the penguin diagrams can not explain $\text{R}_\text{K}$, $\text{R}_{\text{K}^*}$ anomalies, and that the box diagram is required. The experimental constraints for $\text{R}_\text{K}$ and $\text{R}_{\text{K}^*}$ result in new particle mass degeneracy. The contributions of NP to the branching ratios $\text{Br}(\text{B}\to μ^+ μ^-), \text{Br}(\text{b}\to s γ)$ predict results that agree with the experimental limits in the allowed region of the NP scale.
