摘要(英)

We present a detailed analysis together with numerical calculations on one-loop contributions to the electron electric dipole moment from supersymmetry without R parity.
We are interested at class of one-loop contributions are obtained from diagrams involving bilinear-trilinear parameter combinations. The bilinear parameters come into
play through mass mixings induced among the fermions and scalars (slepton and Higgs states), while the trilinear parameter enters through a mass eigenstate e ective coupling vertex. We have made a systematic study of the in
uence of R-parity violating parameters on the one-loop EDM diagrams.
