Quantum Field Theory

Physical Review, 1950
It is usually contended that the quantum theory of fields is intrinsically divergent. The present paper attempts to show that this divergence is due to the perturbation theory generally employed and not to the field theory itself. By means of a minor modification in the perturbation calculations, the divergent integrals may be given appropriate finite ...

Relativistic quantum field theory [PDF]

open access: possiblePhysics Today, 1966
THE RELATIVISTIC QUANTUM theory of fields was born some 35 years ago through the paternal efforts of Dirac, Heisenberg, Pauli and others. It was a somewhat retarded youngster, however, and first reached adolescence 17 years later, an event which we are gathered here to celebrate. But it is the subsequent development and more mature phase of the subject

The Quantum Theory of Fields

1995
In this third volume of The Quantum Theory of Fields, available for the first time in paperback, Nobel Laureate Steven Weinberg continues his masterly exposition of quantum field theory. This volume presents a self-contained, up-to-date and comprehensive introduction to supersymmetry, a highly active area of theoretical physics. The text introduces and

Quantum Field Theory

2015
In this chapter the framework of quantum field theory is introduced. Starting with the equation derived in Chap. 5\( \left[ {{\Phi} (x),\pi (y)} \right] = i\delta \left( {x - y} \right), \)we are able to see that the fields itself are operators. The solutions to the equations of motion for spin 0, 1/2 and 1 are written in terms of their Fourier ...
