RUI: Measurement of the Electron ELectric-Dipole Moment Using Cs and Rb Magnetometers

这项工作将继续实验测量铯原子的电偶极矩，并由此测量电子的电偶极矩(EDM)，作为时间反转对称性的测试。这些实验依赖于新开发的双磁力仪，应该会将现有的电火花测量铯的精度提高两个数量级。这将使电子电火花加工的灵敏度达到10-28e-cm。如果实现这一点，这种新的测量将构成对电子电火花加工最严格的限制，并将显著限制粒子物理超出标准模型。

This work will continue experiments to measure the electric dipole moment of the cesium atom, and from that the electric dipole moment (edm) of the electron, as a test of time- reversal symmetry. These experiments, relying on a newly- developed dual magnetometer, should improve the precision of the existing edm measurement in cesium by two orders of magnitude. This would give a resulting sensitivity to an electron edm of 10-28e-cm. If this is achieved, this new measurement would constitute the most stringent limit on an electron edm and would significantly constrain particle physics beyond the standard model.
