论文摘要
我们仔细地重新审视了KKLT场景的大规模层次结构，并从一个强烈扭曲的喉咙中的反D3-Brane提升术语。首先，我们从通常从克莱巴诺夫 - 斯特雷斯勒的几何形状中直接称为“喉咙拟合到散装的喉咙”而得出结合。通过Demirtas，Kim，McAllister和Moritz（DKMM）提出的机制生成了超电势$ W_ {0} $的较小价值，我们确定了两个可能的DKMM dkmm固定的KKLT场景，以稳定光轴 - dilaton模量。第一种方案破坏了散装和喉咙质量尺度之间的预期层次结构，这意味着隆起的能量尺度大于喉咙中有效理论的物种尺度。此外，它需要一个不自然的tadpole $ n \ sim 10^{7-8} $，这肯定与取消t的tadpole冲突。对于较少受限的第二种情况，可以以最乐观的假设为代价来控制层次结构，这是唯一一个中等大的tadpole $ n \ sim 10^{2-3} $。
We carefully revisit the mass hierarchies for the KKLT scenario with an uplift term from an anti D3-brane in a strongly warped throat. First, we derive the bound resulting from what is usually termed "the throat fitting into the bulk" directly from the Klebanov-Strassler geometry. Generating the small value of the superpotential $W_{0}$ via the mechanism proposed by Demirtas, Kim, McAllister and Moritz (DKMM), we identify two possible DKMM-refined KKLT scenarios for stabilizing the light axio-dilaton modulus. The first scenario spoils the expected hierarchy between the bulk and the throat mass scales and implies that the energy scale of the uplift is larger than the species scale of the effective theory in the throat. Moreover it requires an unnaturally large tadpole $N\sim 10^{7-8}$ that is certainly in conflict with tadpole cancellation. For the less restricted second scenario, the hierarchy can be controlled at the expense of, under the most optimistic assumptions, an only moderately large tadpole $N\sim 10^{2-3}$.
