# New dimensions from gauge-Higgs unification

## TL;DR

This paper explores gauge-Higgs unification models in warped space, predicting new particles and dimensions, with implications for collider experiments and proton decay suppression.

## Contribution

It introduces a gauge-Higgs grand unification framework in SO(11), proposing an additional sixth dimension and new testable predictions for particle physics.

## Key findings

- Predicted new W', Z' bosons around 6-8 TeV.
- Almost identical low-energy phenomenology to the Standard Model.
- Suppressed proton decay in the grand unification model.

## Abstract

The Higgs boson is unified with gauge fields in the gauge-Higgs unification. The $SO(5) \times U(1)$ gauge-Higgs electroweak unification in the Randall-Sundrum warped space yields almost the same phenomenology at low energies as the standard model, and gives many predictions for the Higgs couplings and new $W', Z'$ bosons around $6 \sim 8$ TeV, which can be tested at 14 TeV LHC. The gauge-Higgs grand unification is achieved in $SO(11)$ gauge theory. It suggests the existence of the sixth dimension (GUT dimension) in addition to the fifth dimension (electroweak dimension). The proton decay is naturally suppressed in the gauge-Higgs grand unification.
