Abstract
Effects of Z′ in the SO(5)×U(1) GHU A-model on the fermion pair production processes e^+ e^- → \bar{f} f are explained. In the SO(5) × U (1) GHU model, the Kaluza-Klein excitation modes of γ, Z and the neutral SU(2)R gauge boson appear as Z′s. There are large asymmetries between Z′ couplings with left- and right-handed fermions. Although Z′ mass is 6 – 8 TeV, the significant deviations of the cross sections and forward-backward asymmetries from those in the standard model are predicted at \sqrt{s} = 250 GeV by using the polarised beams.
