An M theory Solution to the Hierarchy Problem

TL;DR

It is shown that strong gauge dynamics also stabilizes the moduli in M theory compactifications on manifolds of G2 holonomy without fluxes, which gives stable vacua with softly broken supersymmetry, grand unification, and a distinctive spectrum of TeV and sub-TeV sparticle masses.

Abstract

An old idea for explaining the hierarchy is strong gauge dynamics. We show that such dynamics {\it also} stabilises the moduli in $M$ theory compactifications on manifolds of $G_2$-holonomy {\it without} fluxes. This gives stable vacua with softly broken susy, grand unification and a distinctive spectrum of TeV and sub-TeV sparticle masses.
