弯曲时空中规范-希格斯统一模型的有效理论

Effective theories of gauge-Higgs unification models in warped spacetime

Yutaka Sakamura

摘要:

我们推导了在弯曲时空中规范-希格斯统一模型的四维有效理论。忽略对波函数的次引导修正,有效作用量可以用简单的形式表示。我们在以前的工作中已经表明,某些希格斯场与其他场的耦合会受到某些因子的抑制,这些因子依赖于标准模型中的值中的$\barθ_H$。这里$\barθ_H$是沿第五维的威尔逊线相位,它表征了电弱对称性破缺。这里导出的有效作用量明确地显示了希格斯扇区的非线性结构,这澄清了这些抑制因子的起源。

英文摘要:

We derive four-dimensional (4D) effective theories of the gauge-Higgs unification models in the warped spacetime. The effective action can be expressed in a simple form by neglecting subleading corrections to the wave functions. We have shown in our previous works that some Higgs couplings to the other fields are suppressed by factors that depend on $\barθ_H$ from the values in the standard model. Here $\barθ_H$ is the Wilson line phase along the fifth dimension, which characterizes the electroweak symmetry breaking. The effective action derived here explicitly shows a nonlinear structure of the Higgs sector, which clarifies the origins of those suppression factors.
