Course Description

This course constitutes the second part of a two-semester introduction to Quantum Field Theory. The topics covered or briefly addressed include:

• fermions (quantization of a Dirac field; Grassmannian path integral; Euclidean Dirac fields; discrete symmetries C,P,T)
• gauge fields (gauge invariance; quantization of gauge fields; Faddeev-Popov determinant and ghosts; effective action and the background field method; asymptotic freedom)
• symmetries (Ward identities; anomalies; BRST invariance)
• systems with a scale hierarchy (power counting; composite operators; operator product expansion)
