TL;DR

This paper investigates signals of $W'$ and $Z'$ bosons predicted by gauge-Higgs unification models at the LHC, deriving constraints on their masses and phases from experimental data and projecting future discovery potential.

Contribution

It provides the first detailed analysis of $W'$ and $Z'$ signals in $SU(3) imes SO(5) imes U(1)$ gauge-Higgs unification models using LHC data, including mass constraints and future reach estimates.

Findings

Constraints on KK mass scale up to 18 TeV with 300 fb$^{-1}$

Potential to explore KK mass scale up to 22 TeV with 3000 fb$^{-1}$

Projections for discovery reach at $ oot s=14$ TeV

Abstract

The $pp\to \{W, W'\} \to l\nu$ and $pp\to \{\gamma, Z, Z'\} \to l^+l^-$ ($l=e,\mu$) processes in the $SU(3)_C\times SO(5)\times U(1)_X$ 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 GUT inspired GHU model up to 18 TeV for the luminosity 300 fb$^{-1}$ and 22 TeV for the luminosity 3000 fb$^{-1}$ at $\sqrt{s}=14$ TeV.
