LHC signals of the SO(5)×U(1) gauge-Higgs unification

“…We analyze Z search of 8 TeV and 14 TeV LHC [10]. In previous section we comment that Z is independent on dark fermions because of universality.…”

“…Our model has Z s which are not the SM Z boson but neutral massive gauge bosons. In this paper we discuss Z search of our model at LHC experiments [10].…”

“…The current non-observation of Z ′ signals puts the limit θ H 0.11. Recently an alternative model with quark-lepton multiplets introduced in the spinor, vector, and singlet representations of SO(5) (referred to as the B-model below) has been proposed, [13] which can be incorporated in the SO (11) gauge-Higgs grand unification. [14] Other variants of the fermion content have also been proposed.…”

Gauge-Higgs Grand Unification

“…[4]- [10] The orbifold structure of the extra-dimensional space is vital to have chiral fermions, and natural realization of dynamical EW symmetry breaking is achieved in the fivedimensional Randall-Sundrum (RS) warped spacetime. The most promising is the SO(5) × U (1) X gauge-Higgs unification in RS, which is consistent with the observation at low energies provided its AB phase θ H < ∼ 0.…”

“…The result is summarized in Table 1. BC at y = 0 with P sp 0 admits parity-even lefthanded (right-handed) modes only for 16 (16) of SO (10), whereas BC at y = L with P sp 1 admits parity-even left-handed (right-handed) modes only for SU (2) L (SU (2) R ) doublets.…”
