Title: SUSY breaking in branes at singularities (or: The octagon rising from the swamp)


After motivating the search for string theory configurations where supersymmetry is spontaneously broken, I will discuss the approach focused on branes at singularities, in the context of the open/closed duality (a.k.a. gauge/gravity correspondence). The search for SUSY breaking configurations is made difficult by the peculiarities of the QFT models of dynamical SUSY breaking models one wants to reproduce with branes, and by the instabilities inherent with the brane construction. I will finally present a configuration, based on a particular singularity (which we dubbed the Octagon), that is the only one to pass all the stability tests. We comment on its properties and possible generalizations, and geometric/supergravity realizations. We will make some comments on the relevance of our results for some Swampland conjectures.
Based on 1909.04682, 2005.09671, 2007.13762, 2009.11291 + work in progress.
