寻找中子的电偶极矩
The quest to find an electric dipole moment of the neutron
摘要：
到目前为止，还没有观察到中子的电偶极矩（nEDM）。为什么它如此之小，在过去的65年里一直没有被发现，这并不容易解释。一般来说，它被认为是破坏电荷和宇称组合对称性（CP）的最敏感的探针之一。这一发现可能会揭示人们对宇宙中物质/反物质不对称性知之甚少的问题。中子EDM可能有一天有助于区分CP破坏的不同来源，结合顺磁性分子，抗磁性原子和其他原子核的测量。本综述概述了搜索nEDM的最重要的概念以及全球范围内的努力的简要概述。
英文摘要：
Until now no electric dipole moment of the neutron (nEDM) has been observed. Why it is so vanishingly small, escaping detection for the last 65 years, is not easy to explain. In general it is considered as one of the most sensitive probes for the violation of the combined symmetry of charge and parity (CP). A discovery could shed light on the poorly understood matter/antimatter asymmetry of the Universe. The neutron EDM might one day help to distinguish different sources of CP-violation in combination with measurements of paramagnetic molecules, diamagnetic atoms and other nuclei. This review presents an overview of the most important concepts in searches for an nEDM as well as a brief overview of the worldwide efforts.
