Lines of Constant Physics in a Five-Dimensional Gauge-Higgs Unification Scenario

TL;DR

This paper investigates a five-dimensional Gauge-Higgs Unification model non-perturbatively, demonstrating spontaneous symmetry breaking, dimensional reduction, and matching experimental mass ratios, while constructing a line of constant physics.

Contribution

It presents the first construction of a line of constant physics in this model, predicting the mass scale of excited states of Higgs and gauge bosons.

Findings

Spontaneous breaking of global symmetry triggers the Higgs mechanism.

Dimensional reduction occurs in the studied phase diagram region.

Mass ratios of Higgs and Z bosons match experimental values.

Abstract

We report on the progress in the study of a five-dimensional SU(2) Gauge-Higgs Unification model. In this non-perturbative study, the Higgs mechanism is triggered by the spontaneous breaking of a global symmetry. In the same region of the phase diagram, we observe both dimensional reduction and the ratio of Higgs and Z boson masses to take the value known from experiment. We present the first results on the construction of a line of constant physics in this region, including the prediction for the mass scale of the first excited states of the Higgs and gauge bosons.
