In this talk, I will address the challenges of obtaining a dS vacua in type IIB flux compactifications that include a warped throat region of Klebanov-Strassler type corresponding to a warped deformed conifold, with an anti-D3-brane sitting at its tip. Previous studies have shown that the dS uplift in the KKLT type scenario in the strongly warped regime where the warping introduces a coupling between the conifold’s deformation modulus and the bulk modulus, may destabilize the closed string moduli unless the tadpole bound is compromised. However, we explore a new regime where the warping term is subdominant. We thus discover a new metastable de Sitter solution within the four-dimensional effective field theory, with full moduli stabilization using a Large Volume Scenario. We discuss the position of this de Sitter vacuum in the string theory landscape.
