Distinct signals of the gauge-Higgs unification in $e^{+}{e}^{-}$ collider experiments

Abstract

Effects of Kaluza-Klein excited neutral vector bosons ($Z^{\prime }$ bosons) in the gauge-Higgs unification on $e^{+}{e}^{-}\to \bar{q}q,{\ell }^{+}{\ell }^{-}$ cross sections are studied, particularly in future $e^{+}{e}^{-}$ collider experiments with polarized beams. Significant deviations in the energy and polarization dependence in $\sigma ({\mu }^{+}{\mu }^{-})$, the lepton forward-backward asymmetry, $R_b(\mu )\equiv \sigma (\bar{b}b)/\sigma ({\mu }^{+}{\mu }^{-})$ and the left-right asymmetry from the standard model are predicted.
