Opis

This is a systemic presentation of quantum field theory from first principles, emphasizing both theoretical concepts and experimental applications.

Recenzje

"...useful for an introductory course in quantum field theory to graduate students. Furthermore it provides a good introduction to the theory of perturbative QCD for research scientists who are interested to work in this field." Paolo Nason, Cern Courier
