摘要
Z' boson vector and axial vector couplings to fermions are studied in terms of anomaly cancellation in the condition of small Z-Z' mixing. The anomaly-free U(1)' charge assignment that parametrized by two independent charges is proposed. Z' decay width to fermion pair Gamma(Z') (f (f) over bar), hadron-to-lepton ratio R'(l), hadron branching ratio R'(q), left-right asymmetry A'(LR) and forward backward asymmetry A'(FB) are investigated. A special sum rule of Z' decay widths is also derived.
