论文摘要
我们在简单的$ 3-3-1 $模型上研究现象学的限制，并违反了Yukawa耦合。这两对三胞胎夫妇夫妇都与Leptons和Quarks在一起，这在Lepton和Quark部门都产生了违反风味的信号。我们已经表明，该模型可以允许大型Higgs Lepton风味侵入率衰减$ h \rightarrowμτ$，并且可以与其他实验性约束（例如$τ\rightarrowμγ$和$（g-2）_ $）达成完美的协议。研究了改变风味的中性电流（FCNC）耦合，Higgs-Quark-Quark耦合对介体混合的贡献。通过保持介子混合的测量，可以增强br $（h \ rightarrow q q^\ prime）$。 $ t \ rightarrow q h $的分支比率可以达到$ 10^{ - 3} $，但可能低至$ 10^{ - 8} $。
We study phenomenological constraints on a simple $3-3-1$ model with flavor violating Yukawa couplings. Both triplets Higgs couple to leptons and quarks, which generates flavor violating signals in both lepton and quark sectors. We have shown that this model can allow for large Higgs lepton flavor-violating rate decay $h \rightarrow μτ$ and also can be reached to perfect agreements with other experimental constraints such as $τ\rightarrow μγ$ and $(g-2)_μ$. The contributions of flavor-changing neutral current (FCNC) couplings, Higgs-quark-quark couplings, to the mesons mixing are investigated. Br$(h \rightarrow q q^\prime )$ can be enhanced with keeping from the measurements of meson mixing. The branching ratio for $t \rightarrow q h$ can reach up to $10^{-3}$, but it could be as low as $10^{-8}$.
