通过Higgs机制和非紧五维的有限电弱相互作用局域化标准模型

Localization of the Standard Model via Higgs mechanism and a finite electroweak monopole from non-compact five dimensions

Masato Arai, Filip Blaschke, Minoru Eto, Norisuke Sakai

摘要:

我们提出了一个最小的和自包含的模型在非紧凑的平面五维本地化的标准模型(SM)上的域壁。规范场的定域化是通过Higgs场在五维拉格朗日量中通过Higgs相关的规范动力学项的凝聚实现的。连接真空与未破缺的规范对称性的畴壁驱动了Higgs凝聚,Higgs凝聚同时提供了电弱对称性破缺和规范场局域化。我们的模型在低能有效理论中预测了更高维的相互作用$|H|^{2n}(F_{μν})^2$。这导致了两个期望:一个是一个新的树级贡献的$H \to γγ$($H \to gg$)衰变的签名是在未来的LHC实验测试。另一个是有限的电弱势,它可以被MoEDAL实验所利用。平移南武-戈德斯通玻色子的相互作用满足低能定理。

英文摘要:

We propose a minimal and self-contained model in non-compact flat five dimensions which localizes the Standard Model (SM) on a domain wall. Localization of gauge fields is achieved by the condensation of Higgs field via a Higgs dependent gauge kinetic term in five-dimensional Lagrangian. The domain wall connecting vacua with unbroken gauge symmetry drives the Higgs condensation which provides both electroweak symmetry breaking and gauge field localization at the same time. Our model predicts higher-dimensional interactions $|H|^{2n}(F_{μν})^2$ in the low-energy effective theory. This leads to two expectations: The one is a new tree-level contribution to $H \to γγ$ ($H \to gg$) decay whose signature is testable in future LHC experiment. The other is a finite electroweak monopole which may be accessible to the MoEDAL experiment. Interactions of translational Nambu-Goldstone boson is shown to satisfy a low-energy theorem.
