Quantum Electrodynamics of Spinless Bosons
All considerations in this book so far have dealt with electrons (or muons) and their antiparticles, i.e. particles with spin 1 /2, which are described by the Dirac equation. The theory of quantum electrodynamics describes the interaction of these particles with each other and with the photon field in a very satisfying way. In principle, nothing prevents us from trying to construct a similar theory also for other kinds of particles. The simplest case is scalar (or pseudoscalar) bosons, which have spin O. In the following we want to develop the theory of the electromagnetic interaction of these particles, which is also known as “scalar electrodynamics”. We can take over many ingredients of the theory from Chapters 2 and 3 either directly or with only marginal modifications.
