Low Energy Supersymmetry from Non-Geometry

TL;DR

This paper explores non-geometric flux compactifications in type II string theories that stabilize all moduli, achieve a high string scale, and generate a low gravitino mass, enabling low energy supersymmetry.

Contribution

It introduces a class of flux compactifications with all moduli stabilized and a dynamically generated low gravitino mass, expanding the landscape of viable string vacua.

Findings

Existence of supersymmetric Minkowski vacua with stabilized moduli

Non-perturbative effects deform Minkowski vacua to AdS vacua with small gravitino mass

Potential for low scale supersymmetry breaking mechanisms

Abstract

We study a class of flux compactifications that have all the moduli stabilised, a high (GUT) string scale and a low (TeV) gravitino mass that is generated dynamically. These non-geometric compactifications correspond to type II string theories on SU(3)xSU(3) structure orientifolds. The resulting superpotentials admit, excluding non-perturbative effects, supersymmetric Minkowski vacua with any number of moduli stabilised. We argue that non-perturbative effects are present and introduce terms in the superpotential that are exponentially suppressed by the same moduli that appear perturbatively. These deform the supersymmetric Minkowski vacua to supersymmetric AdS vacua with an exponentially small gravitino mass. The resulting vacua allow for low scale supersymmetry breaking which can be realised by a number of mechanisms.
