Forward-backward asymmetry on Z resonance in SO(5) x U(1) gauge-Higgs unification

Abstract

We find that the tree-level predictions of the forward-backward production asymmetries on the Z resonance for b and c quarks, A_FB, in an SO(5) x U(1) gauge-Higgs unification model are markedly close to the central values of the Particle Data Group data unlike the standard model. The decay width of Z boson is evaluated and the S and T parameters are discussed.
