On the fermion spectrum of spontaneously generated fuzzy extra dimensions with fluxes

TL;DR

This paper studies a four-dimensional SU(N) gauge theory with fluxes that mimic extra dimensions as fuzzy spheres, revealing the structure of fermion zero modes and their implications for low-energy models.

Contribution

It demonstrates how certain vacua of a gauge theory can produce fuzzy extra dimensions with fluxes, affecting the fermion spectrum and low-energy physics.

Findings

Fuzzy S^2 x S^2 extra dimensions emerge at intermediate scales.

Fluxes induce specific zero modes in the fermion spectrum.

Results suggest potential for mirror models in low-energy physics.

Abstract

We consider certain vacua of four-dimensional SU(N) gauge theory with the same field content as the N=4 supersymmetric Yang-Mills theory, resulting from potentials which break the N=4 supersymmetry as well as its global SO(6) symmetry down to SO(3) x SO(3). We show that the theory behaves at intermediate scales as Yang-Mills theory on M^4 x S^2 x S^2, where the extra dimensions are fuzzy spheres with magnetic fluxes. We determine in particular the structure of the zero modes due to the fluxes, which leads to low-energy mirror models.
