Effect on the electron EDM due to abelian gauginos in SUSY extra

The electric dipole moment of an electron (EDME) is investigated in the supersymmetric extra U(1) models. Neutralino sector is generally extended in these models and then the neutralino contribution will be important for the analysis of the EDME. Kinetic term mixings of abelian gauginos are taken into account in our analysis. Numerical results for the extra U(1) models show that the EDME can be affected by the extra U(1) in a certain range of soft supersymmetry breaking parameters even if the extra U(1) gauge boson is heavy. The EDME may be a clue to find an extended gauge structure in the supersymmetric models. e-mail:suematsu@hep.s.kanazawa-u.ac.jp Recently the standard model(SM) has been confirmed in the incredible accuracy through the precise measurement at LEP. Nevertheless, it has still not been considered as the fundamental theory of particle physics and physics beyond the SM is eagerly explored. Along this line supersymmetrization of the SM is now considered as the most pro..
