QCD中手征对称性的自发破缺传统上是通过低能定理和与实验的比较间接推断的。由于理解了手征随机矩阵理论和手征微扰理论之间意想不到的联系，QCD中手征对称性的自发破缺现在可以从第一原理和晶格模拟中明确地显示出来。在这些讲座中，我给一个介绍的主题，从一个基本的讨论自发打破全球对称性。
Spontaneous breaking of chiral symmetry in QCD has traditionally been inferred indirectly through low-energy theorems and comparison with experiments. Thanks to the understanding of an unexpected connection between chiral Random Matrix Theory and chiral Perturbation Theory, the spontaneous breaking of chiral symmetry in QCD can now be shown unequivocally from first principles and lattice simulations. In these lectures I give an introduction to the subject, starting with an elementary discussion of spontaneous breaking of global symmetries.
