论文摘要
我们获得了通过nilpotent Goldstino形式主义所描述的抗D3 brane uplifting的KKLT和LVS模型中宇宙常数的联合分布。模量稳定（复杂结构和kaehler模量）都被合并，因此我们仅在与真空的点上进行样品。我们的关键输入是通量超电势的分布，字符串耦合和扭曲喉咙的层次结构。在零宇宙常数的极限下，我们发现在KKLT和LVS中，分布都朝着超对称性破裂的较低尺度倾斜。
We obtain the joint distribution of the gravitino mass and the cosmological constant in KKLT and LVS models with anti-D3 brane uplifting described via the nilpotent goldstino formalism. Moduli stabilisation (of both complex structure and Kaehler moduli) is incorporated so that we sample only over points corresponding to vacua. Our key inputs are the distributions of the flux superpotential, the string coupling and the hierarchies of warped throats. In the limit of zero cosmological constant, we find that both in KKLT and LVS the distributions are tilted favourably towards lower scales of supersymmetry breaking.
