在超对称理论中，重态引起的辐射修正会在超对称破缺质量的味结构中留下足迹。我们调查目前和未来的搜索的μ子和电子的EDM可能是敏感的CP破坏和味道失调引起的slepton质量的辐射校正由于右手中微子的跷跷板模型和SU（5）大统一理论的重希格斯三胞胎。当是这种情况下，限制中微子汤川耦合的相关组合。提供了明确的解析表达式，占超对称质量参数的依赖关系。
In supersymmetric theories the radiative corrections due to heavy states could leave their footprints in the flavour structure of the supersymmetry breaking masses. We investigate whether present and future searches for the muon and electron EDMs could be sensitive to the CP violation and flavour misalignment induced on slepton masses by the radiative corrections due to the right-handed neutrinos of the seesaw model and to the heavy Higgs triplets of SU(5) GUT. When this is the case, limits on the relevant combination of neutrino Yukawa couplings are obtained. Explicit analytical expressions are provided which accounts for the dependencies on the supersymmetric mass parameters.
