Query: Fermion pair production at $e^- e^+$ linear collider experiments in GUT
  inspired gauge-Higgs unification   Fermion pair production at $e^-e^+$ linear collider experiments with
polarized $e^-$ and $e^+$ beams is examined in the GUT inspired $SO(5)\times
U(1)\times SU(3)$ gauge-Higgs unification. There arises large parity violation
in the couplings of leptons and quarks to Kaluza-Klein (KK) excited neutral
vector bosons $Z'$s, which leads to distinctive polarization dependence in
cross sections, forward-backward asymmetries, left-right asymmetries, and
left-right forward-backward asymmetries in various processes. Those effects are
detectable even for the KK mass scale up to about 15 TeV at future $e^-e^+$
linear collider experiments with energies 250$\,$GeV to 1$\,$TeV.
