论文摘要
我们认为，在克莱巴诺夫 - 斯特拉斯勒类型的扭曲喉咙的尖端，在混凝土型的IIB calabi-yau压缩的混凝土型calabi-yau压缩中实现了de Sitter Vacua。 kähler模量与扭曲的喉咙的复杂结构模量一起稳定。该体积的呈指数较大，如大容量方案（LVS）。我们分析了EFT参数的条件，使它们处于我们近似值的有效性区域，没有失控的问题，真空吸收了所有一致性约束，例如取消tpole。我们用明显的calabi-yau方向上示出了我们的结果，其中有两个kählermoduli和一个在扭曲的喉咙上的O3平面上的抗纤维，这是戈德斯蒂诺是其唯一的无质量状态。使用$ g_s \ sim 0.2 $和音量$ \ mathcal {v} \ sim 10^4 $在字符串单元中稳定，在字符串单元中稳定下来，证明用于推导相应eft的近似值是合理的。尽管该模型缺乏手性质，但它作为概念证明，被选为抗纤维隆起的最简单实现。
We consider de Sitter vacua realised in concrete type IIB Calabi-Yau compactifications with an anti D3-brane at the tip of a warped throat of Klebanov-Strassler type. The Kähler moduli are stabilised together with the complex structure modulus of the warped throat. The volume is exponentially large as in the large volume scenario (LVS). We analyse the conditions on the parameters of the EFT such that they are in the region of validity of our approximations, there are no runaway problems and the vacua satisfy all consistency constraints, such as tadpole cancellation. We illustrate our results with an explicit Calabi-Yau orientifold with two Kähler moduli and one antibrane on top of an O3-plane in a warped throat, that has the goldstino as its only massless state. The moduli are stabilised with $g_s\sim 0.2$ and volume $\mathcal{V}\sim 10^4$ in string units, justifying the approximation used to derive the corresponding EFT. Although the model lacks chiral matter, it is presented as a proof of concept, chosen to be the simplest realisation of antibrane uplift.
