Candidate de Sitter Vacua in Type IIB String Theory

Explore a high-energy theory seminar on candidate de Sitter vacua presented by Richard Nally from Stanford University at the Institute for Advanced Study. Delve into the construction of type IIB string theory compactifications that yield de Sitter vacua as envisioned by Kachru, Kallosh, Linde, and Trivedi. Examine the specification of explicit Calabi-Yau orientifolds and quantized fluxes, and learn about the derivation of four-dimensional effective supergravity theories. Discover how these theories incorporate the exact flux superpotential, nonperturbative superpotential from Euclidean D3-branes, and Kähler potential. Investigate the inclusion of a Klebanov-Strassler throat region containing a single anti-D3-brane and its role in uplifting to a metastable de Sitter vacuum. Gain insights into the challenges of finding vacua that survive subleading corrections and understanding quantization conditions in this cutting-edge research based on https://arxiv.org/abs/2406.13751.
