In the framework of the flipped 3-3-1 model introduced recently [1], the lepton-flavor-violating (LFV) decay $\mu \rightarrow 3e$ was predicted to have a large branching ratio (Br) close to the recent experimental limit. We will show that the Br of LFV decays of the standard-model-like (SM-like) Higgs boson decays (LFVHD) Br$(h\rightarrow e_ae_b)$ may also be large. Namely, the Br$(h\rightarrow \mu\tau,e\tau)$ can reach values of $\mathcal{O}(10^{-4})-\mathcal{O}(10^{-5})$, which will reach the upcoming experimental sensitivities. On the other hand, for LFV decays of charged leptons (cLFV) $(e_b\rightarrow e_a\gamma)$, the branching ratios are well below experimental bounds.

类似 SM 的希格斯玻色子 $h\rightarrow e_ie_j$ 和 $e_i \rightarrow e_j\, \gamma $ 在翻转的 3-3-1 模型中违反轻子味的衰变

在最近引入的翻转 3-3-1 模型的框架中 [1]，轻子风味违反 (LFV) 衰减 $\mu\rightarrow 3e$ 预计具有接近最近的大分支比 (Br)实验极限。我们将证明标准模型类（SM 类）希格斯玻色子衰变 (LFVHD) 的 LFV 衰变​​ Br$(h\rightarrow e_ae_b)$ 也可能很大。即 Br$(h\rightarrow \mu\tau,e\tau)$ 可以达到 $\mathcal{O}(10^{-4})-\mathcal{O}(10^{-5} )$，这将达到即将到来的实验灵敏度。另一方面，对于带电轻子 (cLFV) $(e_b\rightarrow e_a\gamma)$ 的 LFV 衰变​​，分支比远低于实验界限。
