论文摘要
a $ h^+ w^ - z $顶点，即，将单人充电的物理标量连接到$ w^\ pm的交互，〜z $量规玻色子在树级别不存在，该标量仅组成$ su（2）_l $ doublets。但是，在这种情况下，可以辐射地生成相互作用，其中一个示例是两higgs Doublet模型。在这项研究中，我们将两种双重的双重表观扩展到额外的$ su（2）_l $ scalar Doublets。在赋予适当的离散对称性时，这些额外的双重弹性填充物可以提供成功的暗物质候选者。有趣的是，相同的“深色”标量也可以辐射增强$ H^+ W^ - Z $相互作用的强度。我们在非线性仪表上计算一环的$ h^+ w^ - z $顶点，以消除某些非物理相互作用。尽管所有可能的约束都考虑到了这样的约束，但特别强调了来自暗物质的限制。研究了暗物质可观察到的相关性与$ h^+ w^ - z $相互作用强度之间的相关性。因此，该研究将辐射生成的$ H^+ W^ - Z $顶点连接到暗物质现象学。
An $H^+ W^- Z$ vertex, i.e, the interaction connecting a singly charged physical scalar to the $W^\pm,~Z$ gauge bosons is absent at the tree level in a scalar sector comprising only $SU(2)_L$ doublets. However, the interaction can be generated radiatively in such a case, an example of which is a two-Higgs doublet model. In this study, we extend a two-Higgs doublet scenario by additional $SU(2)_L$ scalar doublets. Upon endowing with appropriate discrete symmetries, these additional doublets so introduced can furnish successful candidates of dark matter. Interestingly, the same "dark" scalars can also radiatively enhance the strength of the $H^+ W^- Z$ interaction. We compute the $H^+ W^- Z$ vertex at one-loop in a non-linear gauge that eliminates certain unphysical interactions. While all possible constraints are taken into account in doing so, particular emphasis is given to the ones stemming from dark matter. Correlations between the dark matter observables and the $H^+ W^- Z$ interaction-strength are studied. The study thus connects a radiatively generated $H^+ W^- Z$ vertex to dark matter phenomenology.
