六维orbifold模型中的希格斯场被确定与一些内部组件的规范场被认为是。我们基于SU（3）电弱规范对称性对所有可能的T-2/Z（N）轨道结构进行了分类。根据轨道的扭曲，可以得到两个、一个或零个希格斯二重态的模型。有一个希格斯二重态的模型特别有趣，因为它们导致希格斯质量的预测是W玻色子质量的两倍：m（H）= 2 m（W）。电弱标度对截止值是二次敏感的，但只能通过非常特定的局部算子。我们详细研究了这些运营商在一个循环的结构，并确定了一类模型，他们不稳定的电弱规模在领先的顺序。这提供了一个非常有前途的框架，构建现实和预测模型的电弱对称性破缺。
Six-dimensional orbifold models where the Higgs field is identified with some internal component of a gauge field are considered. We classify all possible T-2/Z(N) orbifold constructions based on a SU(3) electroweak gauge symmetry. Depending on the orbifold twist, models with two, one or zero Higgs doublets can be obtained. Models with one Higgs doublet are particularly interesting, as they lead to a prediction for the Higgs mass that is twice the W boson mass at leading order: m(H) = 2 m(W). The electroweak scale is quadratically sensitive to the cut-off, but only through very specific localized operators. We study in detail the structure of these operators at one loop, and identify a class of models where they do not destabilize the electroweak scale at the leading order. This provides a very promising framework to construct realistic and predictive models of electroweak symmetry breaking.
