Quantum Field Theory. Volume 2. Modern Applications

The book of an outstanding American scientist, the Nobel Prize winner S. Weinberg Quantum Field Theory is a modern course of quantum field theory, covering both the main provisions of this area of ​​theoretical physics and numerous new ideas and modern methods developed in recent years. In the second volume, a modern presentation of the methods of quantum field theory is given, it is shown how the use of these methods has led to an understanding of weak, strong and electromagnetic interactions of elementary particles. Modern mathematical methods are presented in combination with their applications in the theory of elementary particles and the theory of condensed state of the substance. At the same time, much attention is paid to such issues as a generalized BRST symmetry, the background field method, the effective field method in an annex to the theory of spontaneous violation, symmetry, the method of operator decomposition, superconductivity, theory of critical phenomena, etc. The presentation is accompanied by numerous tasks placed at the end. Kkazhi chapter.
The book is designed for scientists, graduate students, senior students involved in the problems of quantum theory of fields and physics of elementary particles
