我们回顾了基于规范理论的规范-希格斯统一模型，这些规范理论定义在六维时空中，在额外的空间维度上具有S2/Z2拓扑。在外S2/Z2空间上施加了非平凡边界条件。这篇综述考虑了从六维模型构建四维理论的两种情景。一种方案利用了SO(12)规范对称性，并对规范场施加了特殊的对称性条件，而另一种方案采用了E6规范对称性，不需要附加的对称性条件。这两个模型都得到了具有SU(3)×SU(2)L×U(1)Y(×U(1)2)对称性和四维SM费米子的标准类模型规范理论。并对模型的希格斯扇区进行了分析。实现了电弱对称破缺，得到了弱规范玻色子和希格斯玻色子质量。
We review gauge‐Higgs unification models based on gauge theories defined on six‐dimensional spacetime withS2/Z2topology in the extra spatial dimensions. Nontrivial boundary conditions are imposed on the extraS2/Z2space. This review considers two scenarios for constructing a four‐dimensional theory from the six‐dimensional model. One scheme utilizes the SO(12) gauge symmetry with a special symmetry condition imposed on the gauge field, whereas the other employs the E6gauge symmetry without requiring the additional symmetry condition. Both models lead to a standard model‐like gauge theory with the SU(3) × SU(2)L× U(1)Y(×U(1)2) symmetry and SM fermions in four dimensions. The Higgs sector of the model is also analyzed. The electroweak symmetry breaking can be realized, and the weak gauge boson and Higgs boson masses are obtained.
