LECT QUANT FIELD THEORY (2ND ED)

The lectures offer an informal yet comprehensive exploration of quantum field theory, beginning with relativistic one-particle systems and progressing through fundamental concepts such as the Poincaré group and canonical quantization for various gauge theories. Detailed discussions on BRST symmetry, the Higgs phenomenon, and the standard model of electroweak interactions enrich the content. The text also addresses regularization, BPHZ renormalization, and the renormalization group equation, while additional chapters cover Dirac quantization of constrained systems and discrete symmetries for a well-rounded understanding.
