The non-SUSY $Ad{S}_6$ and $Ad{S}_7$ fixed points are brane-jet unstable

Abstract

In six- and seven-dimensional gauged supergravity, each scalar potential has one supersymmetric and one non-supersymmetric fixed points. The non-supersymmetric $Ad{S}_7$ fixed point is perturbatively unstable. On the other hand, the non-supersymmetric $Ad{S}_6$ fixed point is known to be perturbatively stable. In this note we examine the newly proposed non-perturbative decay channel, called brane-jet instabilities of the $Ad{S}_6$ and $Ad{S}_7$ vacua. We find that when they are uplifted to massive type IIA and eleven-dimensional supergravity, respectively, the non-supersymmetric $Ad{S}_6$ and $Ad{S}_7$ vacua are both brane-jet unstable, in fond of the weak gravity conjecture.
