SUSY breaking scales in the gauge-Higgs unification

TL;DR

This paper explores supersymmetric gauge-Higgs unification in warped space, addressing Higgs stability, dark matter implications, and the impact of supersymmetry on the model's parameters and phenomenology.

Contribution

It demonstrates how supersymmetry resolves the Higgs mass discrepancy and predicts specific superpartner masses in gauge-Higgs unification models.

Findings

Stable Higgs boson can serve as dark matter with mass 70-75 GeV.

Supersymmetry allows for a Higgs mass consistent with dark matter requirements.

Predicted stop mass around 300-320 GeV and light electroweak gauginos.

Abstract

In the $SO(5) \times U(1)$ gauge-Higgs unification in the Randall-Sundrum (RS) warped space the Higgs boson naturally becomes stable. The model is consistent with the current collider signatures only for a large warp factor $z_L > 10^{15}$ of the RS space. In order for stable Higgs bosons to explain the dark matter of the Universe the Higgs boson must have a mass $m_h = 70 \sim 75$ GeV, which can be obtained in the non-SUSY model with $z_L \sim 10^5$. We show that this discrepancy is resolved in supersymmetric gauge-Higgs unification where a stop mass is about $300 \sim 320 $GeV and gauginos in the electroweak sector are light.
