KKLT without AdS
Abstract
According to the KKLT scenario, metastable dS vacua are formed as a result of uplifting of supersymmetric AdS vacua by D3 branes. I describe an extended version of this scenario where metastable dS vacua appear after an uplift from a state where the potential of the volume modulus in the absence of D3 branes would be unbounded below. This mechanism may considerably strengthen vacuum stabilization in the early universe.
