论文摘要
Bargmann-Michel-Telegdi方程描述了恒定电磁场中的自旋动力学，可以用异常的磁和电偶极矩升级。升级的方程式保持自洽，洛伦兹式和量规不变。它及其不同的形式已在高度准确性的许多实验中得到了证实。最近，我们在Wentzel-Kramers-Brillouin弱场近似中得出了自旋运动方程，从而为BMT方程增添了伪级校正。升级的方程式再次是自洽的，洛伦兹的融合，衡量不变的，并且没有不需要的文物。预期伪尺度校正很小，并且在超敏化实验中可能变得很重要，例如对伪级量的电偶极矩的测量。也可以解释为什么EDM很难测量，因为此校正项可能会导致电偶极矩的有效筛选。在同一模型中，可以解释假设假磁异常的实验值和理论值之间的差异，即假立校正是这种差异的主要来源。
The spin dynamics in constant electromagnetic fields is described by the Bargmann-Michel-Telegdi equation which can be upgraded with anomalous magnetic and electric dipole moments. The upgraded equation remains self-consistent, Lorentz-covariant and gauge-invariant. It and its different forms have been confirmed in numerous experiments to high degree of accuracy. We have recently derived the spin motion equation within the Wentzel-Kramers-Brillouin weak-field approximation which adds a pseudoscalar correction to the BMT equation. The upgraded equation is again self-consistent, Lorentz-covariant, gauge-invariant, and free of unwanted artifacts. The pseudoscalar correction is expected to be small, and might become important in hypersensitive experiments, like the measurements of electric dipole moments which are themselves related to pseudoscalar quantities. It also becomes possible to explain why EDMs are so difficult to measure, since this correction term might lead to the effective screening of electric dipole moments. Within the same model, it is possible to explain the discrepancy between experimental and theoretical values of muon magnetic anomaly under assumption that the pseudoscalar correction is the dominant source of this discrepancy.
