摘要

我们研究了在五维时空$M^4\ S^1$上与量子引力耦合的$U(1)$规范理论中作为规范场第五分量的希格斯玻色子的有效势的双环有限性。有两种类型的图包括量子引力修正。我们发现实际上只有一种类型的图对希格斯玻色子的有效势有贡献，而且它的大小是有限的。

Graviton loop contribution to Higgs potential in gauge–Higgs unification

We study a two-loop finiteness of an effective potential for a Higgs boson that is the fifth component of a gauge field in an $U(1)$ gauge theory coupled to quantum gravity on the five-dimensional space-time $M^4\times S^1$. There are two types of diagrams including quantum gravitational corrections. We find that only one type of diagram contributes to the effective potential for the Higgs boson in fact and its magnitude is finite.
