论文摘要
These lectures comprise the second half of a quantum field theory course given in 2004. Topics include the path integral, loop expansion, Feynman rules, various regularization methods, renormalization, running couplings and the renormalization group, fixed points and asymptotic freedom, effective action, Coleman-Weinberg effective potential, fermions, the axial anomaly, QED, gauge fixing, nonabelian gauge theories, unitarity,光学定理，斯拉夫诺夫 - 泰勒的身份，杨麦尔斯理论的β函数，渐近自由的启发式衍生，su（n）仪表理论中的intsantons，theta vacua和强大的CP问题。包括23个作业问题。
