项目摘要

In 1998, the head investigator and collaborators have proposed a "Gauge-Higgs Unification" scenario, where Higgs is identified with the extra space component of a higher dimensional gauge field and its mass is protected under the quantum correction, thanks to the higher dimensional gauge symmetry.In this research, the scenario was enlarged and investigated more deeply from various viewpoints.First, it was generalized to "Gravity-Gauge-Higgs Unification" scenario, where the Higgs is identified with the extra space component of a higher dimensional gravity field and its mass is protected by general coordinate invariance.We also investigated the mutual relation between the Gauge-Higgs Unification and the well-known scenario for solving the hierarchy problem, i.e. supersymmetry. Though at the first glance they seem to be completely different, they were found to be somehow related, in the sense that quantum mechanical supersymmetry is hidden in the Gauge-Higgs Unification scenario.Other investigators have also worked out interesting papers in this field. For instance, the attempts to construct a realistic model embodied with this scenario were done from various approach, such as putting the Gauge-Higgs Unification scenario on a curved space-time like 5-dimensional AdS space.

1998年，主要研究人员和合作者提出了一种“规范-希格斯统一”方案，其中希格斯被认为是高维规范场的额外空间分量，由于高维规范对称性，其质量受到量子修正的保护。本研究从多个角度对该方案进行了扩展和更深入的研究。首先，将其推广到“引力-规范-希格斯统一”方案。其中，Higgs被认为是高维引力场的额外空间分量，它的质量受一般坐标不变性的保护。我们还研究了规范-Higgs统一与解决层级问题的著名场景，即超对称性之间的相互关系。虽然乍一看它们似乎是完全不同的，但他们被发现有某种联系，在某种意义上，量子力学的超对称性隐藏在规范-希格斯统一场景中。其他研究人员也在这个领域发表了有趣的论文。例如，构建包含该场景的现实模型的尝试是从不同的方法进行的，例如将规范-希格斯统一场景放在弯曲的时空上，如5维广告空间。
