在这篇文章中，我们重新审视了最近的一些10d和4d参数，表明超对称AdS真空的提升导致了电位的平坦化，阻止了dS真空的形成。我们解释了为什么相应的10维方法是不确定的，需要相当大的修改。我们还表明，虽然平坦化效应可能会发生一些极端值的参数，他们不阻止dS真空的形成范围内的4D KKLT模型的有效性。KL版本的KKLT方案的基础上的赛道超势需要参数小的隆起，这是不受扁平化。我们表明，这种情况下是兼容的弱引力猜想的广泛选择的参数的KL模型。因此，我们的分析结果不支持最近的沼泽地猜想。
In this note we revisit some of the recent 10d and 4d arguments suggesting that the uplifting of supersymmetric AdS vacua leads to a flattening of the potential, preventing the formation of dS vacua. We explain why the corresponding 10d approach is inconclusive and requires considerable modifications. We also show that while the flattening effects may occur for some extreme values of the parameters, they do not prevent the formation of dS vacua within the range of validity of the 4d KKLT models. The KL version of the KKLT scenario based on a racetrack superpotential requires parametrically small uplifting, which is not affected by flattening. We show that this scenario is compatible with the weak gravity conjecture for a broad choice of parameters of the KL model. Thus, the results of our analysis do not support the recent swampland conjecture.
