我们解决的问题，最近观察到的希格斯质量GeV，弱尺度的顺序，是可计算的规范希格斯统一的情况下，作为一个有限的值。在一个平坦的五维时空中，希格斯粒子的质量是可以计算的，在量子修正的规范不变性的保护下，尽管预测的希格斯粒子的质量通常比实际的要小。然而，在六维SU（3）模型中，一个合适的轨道折叠是已知的，导致质量的数量级：在树的水平上，这有一些相似的最小超对称标准模型的相应预测，我们证明，首先通过一般的参数，其次通过明确的计算，即使量子校正的四次自耦合的希格斯场是紫外发散的，它的偏离是可计算的，因此，两个观测量，和，都是可计算的规范-希格斯统一的情况下。本文还讨论了126 GeV的精确值对紧化标度和模型中物质场体质量的影响。
We address the question of whether the recently observed Higgs massGeV, of the order of the weak scale, is calculable as a finite value in the scenario of gauge–Higgs unification. In the scenario formulated on a flat five-dimensional space-time, the Higgs mass is calculable, being protected under the quantum correction by gauge invariance, though the predicted Higgs mass is generally too small compared with. In the six-dimensional SU(3) model, however, a suitable orbifolding is known to lead to a mass of the order of:at the tree level, which has some similarity to the corresponding prediction by the minimal supersymmetric standard model,.We demonstrate first by a general argument and secondly by explicit calculations that, even though the quantum correction to the quartic self-coupling of the Higgs field is UV-divergent, its deviation from that ofis calculable, and therefore two observables,and, are both calculable in the gauge–Higgs unification scenario. The implication of the precise value 126 GeV to the compactification scale and the bulk mass of the matter field in our model is also discussed.
