Abstract

The model (Lagrangian) with a peculiar extra U(1)is clearly presented. The assigned extra U(1) gauge charges give a strong constraint to build Lagrangians. The Z' discovery limits are estimated and predicted at the Tevatron and the LHC. The new contributions of the muon anomalous magnetic moment are investigated at one and two loops, and we predict that the deviation from the standard model may be explained. The electron electric dipole moment could also be generated because of the explicit CP violation effect in the Higgs sector, and a sizable contribution is expected for a moderately sized CP phase(argument of the CP-odd Higgs).
