We study the LHC signals of SO(5)×U(1) gauge-Higgs unification as a beyond the standard model (SM). When the extra dimensional space is not simply-connected, dynamics of the Aharonov-Bohm (AB) phase, θH, in the extra dimension can induce dynamical gauge symmetry breaking by the Hosotani mechanism. The Kaluza-Klein (KK) mass spectra of γ, Z, ZR and Higgs self couplings obey universal relations with θH in the fifth dimension. In our model, three neutral gauge bosons, Z′ bosons, appear at TeV scale. Z′ bosons are the first KK modes ZR(1), Z(1), and γ(1). We analyze Z′ bosons through dilepton events at LHC. For θH = 0.114, the mass and decay width of ZR(1), Z(1), and γ(1) are (5.73, 482), (6.07, 342), and (6.08 TeV, 886 GeV), respectively. For θH = 0.073 their masses are 8.00 ∼ 8.61 TeV. An excess of events in the dilepton invariant mass should be observed in the Z′ search at the upgraded LHC at 14 TeV.
