Abstract

In this chapter we will gain some practical abilities in calculating various interesting quantum-electrodynamical processes that are of great importance. Thus the following chapter consists mainly of examples and problems. First, we start by applying the propagator formalism to problems related to electron-positron scattering. We shall proceed by considering more complicated processes including photons and other particles. As in the original publications of Feynmanl we shall derive general rules for the practical calculation of transition probabilities and cross sections of any process involving electrons, positrons, and photons. These rules, although derived in a nonrigorous fashion, provide a correct and complete description of QED processes. The same set of “Feynman rules” results from a systematic treatment within the framework of quantum field theory.
