Signals of W′ and Z′ bosons at the LHC in the SU(3) x SO(5) x U(1) gauge-Higgs unification

摘要

The pp -> {W, W'} -> l nu and pp -> {gamma, Z, Z'} -> l(+)l(-) (l = e, mu) processes in the SU(3)(C )x SO(5) x U(1)(X) gauge-Higgs unification (GHU) models are studied, where W' and Z' bosons are Kaluza-Klein (KK) exited states of the electroweak gauge bosons. From the experimental data collected at the Large Hadron Collider, constraints on the KK mass scale and the Aharonov-Bohm phase are obtained. One can explore the KK mass scale in the grand unified theory inspired GHU model up to 18 TeV for the luminosity 300 fb(-1) and 22 TeV for the luminosity 3000 fb(-1) at root s = 14 TeV.
