A domain wall bound on AdS flux vacua

Abstract: In this talk, I will consider anti-de Sitter flux vacua interpolated by flux-changing domain walls. Demanding that the tension of such a domain wall be above the ultraviolet cutoff of the effective description, I will derive an upper bound on the anti-de Sitter radius, which we have termed domain wall bound. It translates into a lower bound on the gravitino mass, thus realizing the certain swampland conjectures. I will test the domain wall bound on several examples with a candidate hierarchy of scales: classical flux vacua, racetrack models, LVS and KKLT-like anti-de Sitter vacua. The classical flux vacua and LVS are found to be compatible with the bound. For racetrack and KKLT-like anti-de Sitter vacua, the bound poses a non-trivial constraint on achieving large hierarchies of scales.
