我们最近对电子的电偶极矩(eEDM)设置了新的限制(J Baron et al and ACME collaboration 2014 Science 343 269-272),这代表了对先前限制的数量级改进,并对标准模型的许多违反电荷宇称的扩展进行了更严格的限制。在本文中,我们详细讨论了测量。描述了实验方法和相关装置,以及用于隔离eEDM信号的技术。特别是,我们详细介绍了实验开关被用来抑制可以模仿感兴趣的信号的影响。还描述了用于搜索系统误差的方法以及解释观测到的系统误差的模型。我们简要地讨论了可能的改进实验。
We recently set a new limit on the electric dipole moment of the electron (eEDM) (J Baron et al and ACME collaboration 2014 Science 343 269–272), which represented an order-of-magnitude improvement on the previous limit and placed more stringent constraints on many charge-parity-violating extensions to the standard model. In this paper we discuss the measurement in detail. The experimental method and associated apparatus are described, together with the techniques used to isolate the eEDM signal. In particular, we detail the way experimental switches were used to suppress effects that can mimic the signal of interest. The methods used to search for systematic errors, and models explaining observed systematic errors, are also described. We briefly discuss possible improvements to the experiment.
