论文摘要
在减少几个粒子的EDM上的上限方面取得了成功。即使必须克服重大挑战以进一步提高这些限制，它仍然是检测到标准模型以外的新型交互的最佳机会之一。分析几个示例，我们突出显示了一个共同的线程，该线程在用于EDM检测的不同设置中可见。电偶极矩是CP-或T侵入相互作用的明显后果之一，但是它不是唯一的后果。这些对称性竞争相互作用使得不可避免地伴随EDM引起的旋转进动的额外现象，并且在计划和执行敏感实验时必须考虑它们。在审查了三个典型情况后，我们建议改善检测内在EDM的灵敏度的条件。
The outstanding progress has been made in reducing the upper bounds on EDM of several particles. Even if significant challenges must be overcome to further improve these limits, it is still one of the best chances to detect new type of interactions beyond the standard model. Analyzing several examples, we highlight a common thread that is visible in different set-ups used for the EDM detection. The electric dipole moment is one of the clear consequences of CP- or T-violating interactions, however it is not the only one. These symmetry-violating interactions enable extra phenomena that unavoidably accompany the EDM-induced spin precession, and they must be taken into account in planning and executing sensitive experiments. After reviewing three typical cases, we suggest conditions for improving the sensitivity of detecting the intrinsic EDM.
