本文在具有CP破坏相的SUGRA模型框架下，分析了最近在BNL观测到的电子电偶极矩（de）和μ子磁矩异常（amu）。分析表明，即使d_e为零，也可能存在一个大的Bino质量相（范围从0到2 π）和相应的大的B软断裂质量相（大小约为114 GeV，B -> s \gamma等）。分析中包括了所有的Stau-中性伴子共湮灭过程的遗迹密度约束。
The electron electric dipole moment (d_e) and the muon magnetic moment anomaly (a_{\mu}) recently observed at BNL are analyzed within the framework of SUGRA models with CP violating phases at the GUT scale. It is seen analytically that even if d_e were zero, there can be a large Bino mass phase (ranging from 0 to 2 \pi) with a corresponding large B soft breaking mass phase (of size ~ 114 GeV, b -> s \gamma, etc.) and relic density constraints with all stau-neutralino co-annihilation processes are included in the analysis.
