    Abstract: 本篇論文詳述了在不包含R-parity 的超對稱標準模型下, 一階 (one loop) 費曼圖 對電子電耦極矩的貢獻. 我們著重於夸克-純量場一階圈圖的貢獻. 給出了解析解和電腦模擬的結果. 我們討論了違反R-parity所造成的中子電耦極矩的貢獻之結構和其主要特徵. 特別是違反了 R-parity 的 (Bi*).(λ’ijk) 和 (μi*).(λ’ijk) 兩組參數的組合. 對中子電耦極矩形成主要之貢獻.違反 R-parity 的參數或 CKM 矩陣的複數相位是所需的電荷及宇稱的破壞源. We present a detailed analysis together with exact numerical calculations on one-loop contributions to the neutron electric dipole moment from supersymmetry without R parity, focusing on the quark-scalar loop contributions. Complete formulae are given for the various contributions through the quark dipole operators. We discuss the structure and main features of the R-parity violating contributions. In particular, the parameter combinations $B_i^*lambda^{prime}_{ijk}$ and $mu_i^*lambda^{prime}_{ijk}$, under the optimal parametrization adopted, are shown to be responsible for the R-parity violating contributions. The sources of the necessary CP violation can come from R-parity violating parameters or the complex phase in the CKM matrix itself.
