摘要

μ子是自旋为1/2的第二代轻子的基本粒子。介子的自旋通过偶极矩与电磁场相互作用。利用粒子物理的标准模型，可以对介子的磁偶极矩进行精确的预测。在标准模型下估计电偶极矩非常小。对这些介子偶极矩的精确测量及其与理论的比较使我们能够研究超越粒子物理标准模型的新物理现象。本文综述了介子偶极矩的测量和下划线物理。

Anomalous Magnetic Moment and Electric Dipole Moment of Muon

Muon is an elementary particle that belongs to the second-generation lepton with spin 1/2. Spin of muon inter-acts with electro-magnetic ﬁelds through dipole moments. A precise prediction on magnetic dipole moment of muon is possible by using the standard model of particle physics. The electric dipole moment is estimated to very small under the standard model. Precision measurements of these dipole moments of muon and its comparison to theory allow us to study new physics phenomena beyond the standard model of particle physics. Measurements of muon dipole moments and underlined physics are reviewed in this paper.
