论文摘要
我们研究CP违反了2种HIGGS Doublet模型，作为从$ SU（3）_l \ otimes U（1）_x $ g量规对称的模型中出现的有效理论。由于电动对称性的扩展，Yukawa相互作用的特征结构在Electroweak量表上出现了新的CP违反阶段。在这种情况下，带电的Higgs玻色子环在一环水平上为中子电偶极矩（NEDM）提供了显着且相当大的贡献。我们发现，NEDM的预测可能比当前的上限略小，$ {\ cal o}（10^{ - 26}）\，e \，\，\ text {cm} $，被带电的Higgs boson和新的CP违反阶段的大量，违反了几百ggev和$ \ Mathcal的限制，$ \ Mathcal（1）（1）（1）（1）（1）（1）（1）（1）混合，$ b \ tox_sγ$衰减和当前LHC数据。
We investigate CP violating 2 Higgs doublet models as an effective theory emerging from models with an $SU(3)_L \otimes U(1)_X$ gauge symmetry. Because of the extension of the electroweak symmetry, a characteristic structure of Yukawa interactions appears with new CP violating phases at the electroweak scale. In this scenario, the charged Higgs boson loop provides dominant and sizable contributions to the neutron electric dipole moment (nEDM) at one-loop level. We find that the prediction of the nEDM can be slightly smaller than the current upper limit, ${\cal O}(10^{-26})\,e\,\text{cm}$, with the mass of the charged Higgs boson and new CP violating phases to be a few hundred GeV and $\mathcal{O}(1)$, respectively, under the constraints from the meson mixings, the $B \to X_s γ$ decay and current LHC data.
