论文摘要
我们考虑$α'^2 $曲率校正对NS5-Brane的作用，该校正在Kachru，Pearson和Verlinde（KPV）的扭曲抗D3-Brane Uplifts的标准性分析中起关键作用。这样的校正可以极大地改变KPV分析。我们发现，对于$α'^2 $ - 校正足够小，可以恢复基本上的前阶kPV电位，需要一个令人惊讶的大$ s^3 $半径，对应于$ g_sm> 20 $。在大卷场景（LVS）的上下文中，这意味着至少$ \ MATHCAL {O}（10^3-10^4）$的D3 tADpole。但是，大型$α'^2 $ - 校正不一定会破坏KPV的隆起。相反，随着曲率校正降低了棕褐色的张力，一种新颖的升起机制表明，通过调整曲率校正来实现隆起的较小性。基础假设的一个关键是存在$ g_s $的密集置换。这种新机制不需要深层扭曲的喉咙，从而避开了振奋KKLT和LVS的主要困难。但是，以上所有内容都必须视为对可能性的初步探索，因为目前，并非已知所有相关校正。
We consider $α'^2$ curvature corrections to the action of an NS5-brane which plays the key role in the metastability analysis of warped anti-D3-brane uplifts by Kachru, Pearson and Verlinde (KPV). Such corrections can dramatically alter the KPV analysis. We find that for the $α'^2$-corrections to be sufficiently small to recover essentially the leading-order KPV potential one needs a surprisingly large $S^3$ radius, corresponding to $g_sM > 20$. In the context of the Large Volume Scenario (LVS) this implies a D3-tadpole of at least $\mathcal{O}(10^3-10^4)$. However, large $α'^2$-corrections do not necessarily spoil the uplift in KPV. Rather, as the curvature corrections lower the tension of the brane, a novel uplifting mechanism suggests itself where the smallness of the uplift is achieved by a tuning of curvature corrections. A key underlying assumption is the existence of a dense discretuum of $g_s$. This new mechanism does not require a deep warped throat, thereby sidestepping the main difficulty in uplifting KKLT and LVS. However, all of the above has to be treated as a preliminary exploration of possibilities since, at the moment, not all relevant correction at the order $α'^2$ are known.
