本文讨论了在含有奇质量费米子的轨道折叠上紧化的规范-希格斯统一模型中费米子的反常磁矩。算符分析意味着反常磁矩应该是有限的和可预测的，即使高维规范理论是不可重正化的。我们的主要目的是澄清各种类型的费曼图中出现的紫外发散的抵消机制。在非零的卡鲁扎-克莱因模式中，在希格斯机制中，发散的抵消发生在伙伴的贡献之间，以形成大质量的规范玻色子。也有人认为，取消可能是由于量子力学的超对称性隐藏在规范-希格斯统一的场景。
We discuss the anomalous magnetic moment of fermion in a realisticmodel of gauge-Higgs unification compactified on an orbifoldincluding-odd bulk mass for fermions. An operator analysis implies that the anomalous magnetic moment should be finite and predictable, even though higher dimensional gauge theories are nonrenormalizable. Our main purpose is to clarify the cancellation mechanism of the UV divergences appearing in various types of Feynman diagrams. The cancellation of divergence turns out to take place between the contributions of the partners in the Higgs-like mechanism present in the nonzero Kaluza-Klein modes to form massive gauge bosons. It is also argued that the cancellation may be attributed to the quantum mechanical supersymmetry hidden in the scenario of gauge-Higgs unification.
