E-mail: [email protected], [email protected], [email protected] Abstract: We generalize the swampland criterion forbidding stable non-supersymmetric AdS vacua and propose a new swampland conjecture forbidding stable non-supersymmetric “locally AdS” warped throats. The conjecture is motivated by the properties of systems of fractional D3-branes at singularities, and can be used to rule out large classes of warped throats with supersymmetry breaking ingredients, and their possible application to de Sitter uplift. In particular, this allows to reinterpret the runaway instabilities of the gravity dual of fractional branes in the dP1 theory, and to rule out warped throats with Dynamical Supersymmetry Breaking D-brane sectors at their bottom. We also discuss the instabilities of warped throats with supersymmetry broken by the introduction of anti-orientifold planes. These examples lead to novel decay mechanisms in explicit non-supersymmetric examples of locally AdS warped throats, and also of pure AdS backgrounds.

Introduction: Quantum Gravitational String Phenomenology
The recent flurry of activity, largely triggered by [1–3], in constraining phenomenological string model building using Quantum Gravity swampland criteria [4–11] (see [12] for a recent review) is giving birth to an emerging field, which can deservedly claim the designation of Quantum Gravitational String Phenomenology. The application of constraints convincingly argued to hold in any theory of Quantum Gravity is leading to new breakthroughs. In particular, the Weak Gravity Conjecture (WGC) [6] (see [1–3, 13–26] for different formulations and applications
