Near-brane SU(6) origin Higgs in Scherk-Schwarz breaking of five-dimensional SU(6) GUT

TL;DR

This paper presents a five-dimensional SU(6) GUT model with Scherk-Schwarz symmetry breaking that naturally generates a Higgs boson near the brane, unifies couplings, and explains the Higgs origin from GUT scale.

Contribution

It introduces a novel orbifold-based symmetry breaking mechanism in 5D SU(6) GUT that leads to a natural origin of the Higgs and correct unification scales.

Findings

Successful symmetry breaking to Standard Model-like groups.

Predicted Higgs mass range consistent with observations.

Achieved gauge coupling unification at the compactification scale.

Abstract

The symmetry breaking of five-dimensional SU(6) GUT is realized by Scherk-Schwarz mechanisms through trivial and pseudo nontrivial orbifold S1/Z2 breakings to produce dimensional deconstruction 5D SU(6) \rightarrow4D SU(6). The latter also induces near-brane weakly-coupled SU(6) Baby Higgs to further break the symmetry into SU(3)C \otimes SU(3)H \otimes U(1)C. The model successfully provides a scenario of the origin of (Little) Higgs from GUT scale, produces the (intermediate and light) Higgs boson with the most preferred range and establishes coupling unification and compactification scale correctly.
