论文摘要
我们通过研究沿正规超级重力背景的分支的亚稳态真空吸引力来识别出参数较小的延伸，这些分支是双重至四维狭窄场理论的。该分支还包括稳定且不稳定的解决方案。前一个特殊情况涵盖了威特（Witten）提出的几何形状，作为监禁的全息模型。后者通过增强双场理论中的冷凝水来接近超对称溶液。相转换将稳定背景的空间与亚稳态的空间分开。在相变的附近，最轻的标量状态之一继承了Dilaton的某些特性，尽管不是特别轻。
We identify a parametrically light dilaton by studying the perturbations of metastable vacua along a branch of regular supergravity backgrounds that are dual to four-dimensional confining field theories. The branch includes also stable and unstable solutions. The former encompass, as a special case, the geometry proposed by Witten as a holographic model of confinement. The latter approach a supersymmetric solution, by enhancing a condensate in the dual field theory. A phase transition separates the space of stable backgrounds from the metastable ones. In proximity of the phase transition, one of the lightest scalar states inherits some of the properties of the dilaton, despite not being particularly light.
