论文摘要
我们提出了两种类型的障碍，用于在超对称理论中构建保姆空间，这些障碍是有效的量子重力理论。第一个障碍涉及在超级实力延长的超级重力中的临界点。我们表明，所有这些临界点具有相同顺序的哈勃尺度或以上是磁性弱重力构指定的紫外线截止量。第二个障碍涉及戈德斯蒂诺（Goldstino）在具有非线性实现的超对称性的模型中的动力学，例如涉及抗凝胶的弦模型。我们使用精确的重新规定方法表明，Goldstino部门对冷凝水的形成具有不稳定的不稳定，这可能对涉及反夸张提升的De Sitter结构产生重要的定性后果。
We present two types of obstacles for constructing de Sitter space in supersymmetric theories that appear as effective theories of quantum gravity. The first obstacle concerns de Sitter critical points in extended supergravity with charged massless gravitini. We show that all such critical points have a Hubble scale of the same order or above the UV cutoff dictated by the magnetic Weak Gravity Conjecture. The second obstacle concerns the dynamics of the goldstino in models with non-linearly realized supersymmetry, such as string models involving anti-branes. We show, using an exact renormalization group approach, that the goldstino sector has an instability toward the formation of condensates, which may have important qualitative consequences for de Sitter constructions involving anti-brane uplifts.
