- 論文の詳細を見る
The low energy phenomenology of the extra U(1) model arising from the E_8×E_8 superstring theory is studied. In the extra U(1) model with an intermediate scale, specific extra U(1) charge assignments are required from proton stability and fermion mass spectra. Masses of two Z bosons and a mixing angle are constrained by the recent experimental data in p^^-p collision, in e^+e^- annihilation and in neutrino scattering. The extra U(1) model explains observed values of R_ν=σ_<NC>(ν)/σ_<cc>(ν) and A_<FB>(e^+e^-→μ^+μ^-) successfully but the standard model does not. It is also found that the extra U(1) model based on the grand desert scenario is phenomenologically unfavorable.
