规范Higgs统一与暗物质的左右模型

Left Right Model from Gauge Higgs Unification with Dark Matter

Francisco J. de Anda

摘要:

基于规范Higgs与规范群$SO(5)\times U(1)$统一的思想,提出了Randall-Sundrum时空中的五维模型.我们得到了一个具有稳定标量的左右对称模型,因此是暗物质的候选者。这个纯量标量通过细谷机制获得真空期望值,该真空期望值将质量给予体中的顶夸克。所有其他来自标准模型的费米子都定域在膜上,并从膜定域标量的真空期望值获得它们的质量。这个标量符合观测到的希格斯玻色子数据。我们能够拟合所有的标准模型观测值,同时避开约束。

英文摘要:

We propose a five dimensional model based on the idea of Gauge Higgs Unification with the gauge group $SO(5)\times U(1)$ in Randall-Sundrum spacetime. We obtain a Left-Right symmetric model with a stable scalar therefore, a dark matter candidate. This scalar scalar obtains a vacuum expectation value which gives mass to the top quark in the bulk through the Hosotani Mechanism. All the other fermions from the Standard Model are localized on a brane and obtain their mass from the vacuum expectation value of a brane localized scalar. This scalar fits the observed Higgs boson data. We are able to fit all the Standard Model observables while evading constraints.
