Geometric Transitions and Dynamical SUSY Breaking

TL;DR

This paper demonstrates how geometric transitions in string theory can model dynamical supersymmetry breaking, translating non-perturbative effects into classical flux superpotentials for simplified analysis and engineering of SUSY-breaking models.

Contribution

It introduces a geometric transition framework that captures non-perturbative SUSY breaking effects as classical flux superpotentials, simplifying the analysis of such phenomena.

Findings

Geometric transitions effectively model non-perturbative superpotentials.

Stringy instanton effects can be understood through classical flux dynamics.

The approach enables engineering of canonical SUSY-breaking models.

Abstract

We show that the physics of D-brane theories that exhibit dynamical SUSY breaking due to stringy instanton effects is well captured by geometric transitions, which recast the non-perturbative superpotential as a classical flux superpotential. This allows for simple engineering of Fayet, Polonyi, O'Raifeartaigh, and other canonical models of supersymmetry breaking in which an exponentially small scale of breaking can be understood either as coming from stringy instantons or as arising from the classical dynamics of fluxes.
