论文摘要
几乎所有用较小的宇宙常数构建De Sitter真空的建议都涉及稳定模量的通量压缩。这些给出了ADS真空吸尘器，通过在紧凑型歧管的某些区域中添加抗植物，可以将其提升到Sitter。然而，抗植物是充电，奇异的，并且与紧凑型成分非凡相互作用。这可能使De Sitter构造无效。在这封信中，我们构建了一种新的成分，用于将广告解决方案升级到Sitter，该成分是中性，光滑且无光平的，因此绕过了抗纤维隆起的一些问题。
Almost all proposals to construct de Sitter vacua with a small cosmological constant involve flux compactifications with stabilized moduli. These give AdS vacua, which are uplifted to de Sitter by adding antibranes in certain regions of the compactification manifold. However, antibranes are charged, singular and interact nontrivially with other ingredients of the compactification; this can invalidate the de Sitter construction. In this Letter, we construct a new ingredient for uplifting AdS solutions to de Sitter, which is neutral, smooth and horizonless, and therefore bypasses some of the problems of antibrane uplift.
