论文摘要
我们展示了一种新型的取消对电子和中子电偶极矩（EDM）的贡献，该贡献发生在三种HIGGS Doublet模型（3HDMS）中，当时CP违规出现在带电的HIGGS部门中。当模型中的两个物理带电的Higgs玻色子在质量中退化时，取消效果变得精确。但是，根据模型参数，10 \％水平的退化足以避免电子和中子EDM上的电流界限。我们证明，可行的参数空间仍然保留，这两个带电的Higgs玻色子都比500 GEV较轻和大型CP侵入阶段，同时还满足了从扰动性和实验性的理论约束，从$ \ bar {b} \ to x_sγ$和Direct搜索。
We demonstrate a new type of cancellation of contributions to the electron and neutron electric dipole moments (EDMs) that occurs in three Higgs doublet models (3HDMs) when CP violation appears in the charged Higgs sector. The cancellation becomes exact when the two physical charged Higgs bosons in the model are degenerate in mass. Depending on the model parameters, degeneracies at the 10\% level are however sufficient to evade current bounds on the electron and neutron EDMs. We demonstrate that viable parameter space remains with both charged Higgs bosons lighter than 500 GeV and large CP-violating phases while also satisfying theoretical constraints from perturbativity and experimental ones from $\bar{B} \to X_s γ$ and direct searches.
