Junwu Huang, John March-Russell

TL;DR
This paper develops a supersymmetric extension of the Standard Model with higher-dimensional mechanisms, achieving precise gauge unification and predicting new TeV-scale particles, with implications for LHC experiments.
Contribution
It constructs a unified supersymmetric model using Scherk-Schwarz supersymmetry breaking with precise gauge coupling predictions and extended unification to a 6D theory.
Findings

Squarks predicted in the 1.4-2.3 TeV range
Abstract
Maximally Natural Supersymmetry, an unusual weak-scale supersymmetric extension of the Standard Model based upon the inherently higher-dimensional mechanism of Scherk-Schwarz supersymmetry breaking (SSSB), possesses remarkably good fine tuning given present LHC limits. Here we construct a version with precision unification: is predicted to by unifying into a 5D theory at a Kaluza-Klein scale of , where SSSB is simultaneously realised. Full unification with is accommodated by extending the 5D theory to a supersymmetric gauge theory on a 6D rectangular orbifold at . TeV-scale states beyond the SM include exotic charged fermions implied by with masses…
