An Exceptional SSM from E6 Orbifold GUTs with intermediate LR symmetry

TL;DR

This paper introduces a class of E6 orbifold GUTs that naturally produce an exceptional supersymmetric standard model with exotic particles and a TeV-scale Z' boson, achieved via a two-step unification process.

Contribution

It presents a novel E6-based orbifold GUT framework that incorporates intermediate symmetry breaking to realize an exceptional supersymmetric standard model with specific low-energy features.

Findings

Achieves gauge unification through two-step symmetry breaking.

Predicts TeV-scale Z' boson and exotic particles.

Provides a consistent model with phenomenological implications.

Abstract

We propose a class of E6-based local orbifold Grand Unified Theories (GUTs) which yield an exceptional supersymmetric standard model as their low energy theory including leptoquark and unhiggs exotics and a Z' at the TeV scale. Unification is achieved in two steps through an intermediate scale symmetry breaking.
