论文摘要
我们认为，在IIB型字符串理论的大容量场景中，DS Vacua容易受到各种未抑制的曲率，翘曲和$ G_S $校正的影响。通常，我们可以解决这些校正如何影响两个Kähler模量，conifold模量和描述抗桥梁升高的Nilpotent的超模量的4D EFT中的模量，真空能和模量质量。我们的分析表明，在相关表达式中，参数校正比从脱壳电位中抑制的表达式更大。某些校正根本没有任何参数抑制，这使得它们对于候选DS真空特别危险。原则上可以将其他类型的校正缩小，以进行适当的参数选择。但是，我们在一个明确的模型中表明，当真空能为正时，所有校正都无法进行。我们认为的一些校正也与非苏绝端广告真空吸尘器的稳定性有关。
We argue that dS vacua in the LARGE-volume scenario of type IIB string theory are vulnerable to various unsuppressed curvature, warping and $g_s$ corrections. We work out in general how these corrections affect the moduli vevs, the vacuum energy and the moduli masses in the 4D EFT for the two Kähler moduli, the conifold modulus and a nilpotent superfield describing the anti-brane uplift. Our analysis reveals that the corrections are parametrically larger in the relevant expressions than one might have guessed from their suppression in the off-shell potential. Some corrections appear without any parametric suppression at all, which makes them particularly dangerous for candidate dS vacua. Other types of corrections can in principle be made small for appropriate parameter choices. However, we show in an explicit model that this is never possible for all corrections at the same time when the vacuum energy is positive. Some of the corrections we consider are also relevant for the stability of non-supersymmetric AdS vacua.
