Description
In this talk I will discuss recently discovered challenges for dS vacua in the Large Volume Scenario and the anti-D3-brane uplift. In particular, I will discuss the effect of $\alpha'$ corrections on the metastability condition of the NS5-brane at the tip of a the Klebanov-Strassler throat which is crucial for the anti-D3-brane uplift. Thereby, we will discover how $\alpha'$ corrections to NS5-branes suggest a novel uplifting mechanism.
