Stability, Tunneling and Flux Changing de Sitter Transitions in the Large Volume String Scenario

Understand

We study the non-perturbative stability of the Large Volume Scenario (LVS) of IIB string compactifications, by analysing transitions mediated by the Brown-Teitelboim (BT) brane nucleations and by Coleman De Luccia tunneling (CDL).

• We find that, as long as the effective field theory description holds, the LVS AdS minima are stable despite being non-supersymmetric.
• This opens the possibility of having a CFT dual.
• Metastable de Sitter vacua behave differently depending on the uplifting mechanism.
