SUSY Breaking through Compactification

TL;DR

This paper introduces a novel mechanism for spontaneous supersymmetry breaking via compactification on extra dimensions with nontrivial topology, leading to unique vacuum structures and spontaneous translational symmetry breaking.

Contribution

It presents a new supersymmetry breaking mechanism that leverages extra-dimensional topology, revealing distinct vacuum structures and spontaneous symmetry breaking phenomena.

Findings

Existence of a phase with spontaneously broken translational invariance.

Different vacuum structures depending on global symmetries.

New features arising from the proposed mechanism.

Abstract

We propose a new mechanism of spontaneous supersymmetry breaking. The existence of extra dimensions with nontrivial topology plays an important role. We investigate new features resulting from this mechanism. One noteworthy feature is that there exists a phase in which the translational invariance for the compactified directions is broken spontaneously. The mechanism we propose also yields quite different vacuum structures for models with different global symmetries.
