Theory of Fundamental Interactions

This textbook on quantum electrodynamics focusses on the theory of fundamental physical interactions and the elementary particles which are subject to these interactions and to leptons and hadrons. Topics presented include: general methods of quantization of physical fields, including the bose, fermi and gauge fields; and the methods for eliminating divergences arising in the modern theory of interacting fields and quantum electrodynamics (i.e. theory of processes involving electrons and photons). In addition both Einstein's theory of gravitation and theory of superfields are developed in terms of non-abelian gauge fields. The idea of the grand unification of the fundamental interactions is also presented. The book should be of use to researchers in high energy physics and students in elementary particle physics.
