论文摘要
我们讨论了KK模式对跨词诱导的力的跨界长度尺度$ r _ {\ rm c} $的贡献，当solitonic背景字段给出brane时。我们在一个5D标量模型中工作，具有模拟DGP模型的域壁背景。尽管有无限的KK模式，但由于对域壁环境空间的翘曲效果，交叉尺度仍然有限。 KK模式的包含在模型参数之间放宽了层次结构，这是实现现象学上可行的尺寸$ r _ {\ rm c} $所需的。我们还讨论了非平凡的dilaton背景是否会放大$ r _ {\ rm c} $。
We discuss contributions of the KK modes to the crossover length scale $r_{\rm c}$ for the brane-induced force when the brane is given by a solitonic background field. We work in a 5D scalar model with a domain-wall background that mimics the DGP model. In spite of the infinite number of the KK modes, the crossover scale remains finite due to the warping effect on the ambient space of the domain wall. The inclusion of the KK modes relaxes the hierarchy among the model parameters that is required to realize a phenomenologically viable size of $r_{\rm c}$. We also discuss whether a nontrivial dilaton background enlarges $r_{\rm c}$ or not.
