Brane annihilation in non-supersymmetric strings

Understand

In this paper we study non-perturbative instabilities in Anti de-Sitter vacua arising from flux compactifications of string models with broken supersymmetry.

• In the semi-classical limit, these processes drive the vacua towards lower fluxes, which translate into higher curvatures and higher string couplings.
• In order to shed some light on this regime, we provide evidence for a description in terms of branes, which generate near-horizon AdS throats.
• To this end, we study the attractor properties of the geometries near the throat, and we also characterize their asymptotics away from it.
