论文摘要
在本文中，我们调查了$ u（1）$ gauge字段在类似Randall-Sundrum的Braneworld型号上的本地化。 $ u（1）$量规场的本地化很重要，因为它在脑界理论中起着基本作用。为了实现本地化，我们提出了一种新颖的动作，并在$ u（1）$ gauge场和重力之间进行非最小的耦合。我们发现，仪表场的质谱是连续的，没有零质量模式和大型模式之间没有任何差距，除了零质量模式外，所有大型模式均未定位在Brane上。此外，巨大的模式具有负平方质量，表明它们是速度的。我们的分析可以应用于五维时空的薄薄且厚的Braneworld场景，只要是渐近的抗DE保姆。
In this paper, we investigate the localization of the $U(1)$ gauge field on Randall-Sundrum-like braneworld models. The localization of the $U(1)$ gauge field is important because it plays a fundamental role in the branworld theories. To achieve the localization, we propose a novel action with a non-minimal coupling between the $U(1)$ gauge field and gravity. We find that the mass spectrum of the gauge field is continuous, without any gap between the zero-mass mode and the massive modes, and except for the zero-mass mode all the massive modes are not localized on the brane. Furthermore, the massive modes have negative squared masses, indicating they are tachyonic. Our analysis can be applied to a wide range of thin and thick braneworld scenarios, provided that the five-dimensional spacetime is asymptotically anti-de Sitter.
