摘要:

规范-希格斯统一是解决标准模型中的层次问题的重要方案之一。近年来,扭曲背景上的场景吸引了许多关注,因为在这个框架中有很大的可能性来自然地构建一个真实的模型。然而,众所周知,希格斯场的有效势,这是最重要的预测的情况下,是不容易计算的扭曲的背景,因为卡鲁扎-克莱因粒子的质量是不分析获得。本文导出了有效势的实用公式。这些公式使我们能够很容易地计算出希格斯粒子的质量,从而在规范-希格斯统一的情况下构造一个真实的模型。使用得到的公式,我们计算了几个边界条件下的体费米子的贡献。我们还表明,大量的费米子,这在orbifold图片不允许的边界条件,不有助于有效的潜力。

英文摘要:

The gauge-Higgs unification is one of influential scenarios to solve the hierarchy problem in the Standard Model. Recently, the scenario on the warped background attracts many attentions due to a large possibility to construct a realistic model naturally in this framework. It is, however, well known that the effective potential for the Higgs field, which is the most important prediction of the scenario, is not easy to calculate on the warped background, because masses of Kaluza-Klein particles are not obtained analytically. In this article, we derive useful formulae for the effective potential. The formulae allow us to calculate the Higgs mass easily, thus to construct a realistic model in the gauge-Higgs unification scenario on the warped background. Using obtained formulae, we calculate contributions from bulk fermions with several boundary conditions. We also show bulk fermions, which have boundary conditions not allowed in the orbifold picture, do not contribute to the effective potential.
