论文摘要
我们讨论了具有扩展量规对称组$ su（2）\ times su（2）\ times u（1）$的模型的结构，并具有相应丰富的电动electroweak对称性断裂结构。尽管模型中具有额外的标量自由度，但额外的量规组$ su（2）$及其相关的重型向量玻色子的存在可确保对称破裂后模型的标量频谱与两个Higgs Doublet模型的标量相同。我们构建模型并讨论其含义，特别是与2HDM相反的与此类模型相关的现象学。
We discuss the structure of a model with an extended gauge symmetry group $SU(2)\times SU(2)\times U(1)$ with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the model, the presence of the extra gauge group $SU(2)$ and its associated heavy vector bosons ensures that the scalar spectrum of the model after symmetry breaking is identical to that of the Two Higgs Doublet Models. We construct the model and discuss its implications, specifically the phenomenology associated with this class of models in contrast to the 2HDM.
