LECT QUANT FIELD THEORY (2ND ED)

The book presents an informal and personal exploration of quantum field theory through lectures from a two-semester course. It begins with relativistic one-particle systems and progresses to fundamental concepts such as the Poincaré group and canonical quantization for various theories. Key topics include covariant quantization and BRST symmetry, the Higgs phenomenon, and the standard model of electroweak interactions. Additionally, it covers regularization and renormalization techniques, alongside discussions on Dirac quantization of constrained systems and discrete symmetries for a comprehensive understanding.
