Effect on the Electron EDM Due to Abelian Gauginos in SUSY Extra U(1) Models
Abstract
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 the neutralino contribution will then 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.
