In the SO(5)×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 for a large warp factor zL>1015of the RS space. In order for stable Higgs bosons to explain the dark matter of the Universe the Higgs boson must have a mass mh=70-75 GeV, which can be obtained in the non-SUSY model with zL~105. We show that this discrepancy is resolved in supersymmetric gauge-Higgs unification where a stop mass is about 300-320 GeV and gauginos in the electroweak sector are light. © 2012 Elsevier B.V.
