Why do We Need Local Gauge Invariance in Theories with Vector Particles? An Introduction
During the last decennium it has become more and more clear that gauge theories play a decisive role in elementary particle physics. Indeed, the most general possible theory for a finite class of particle types, with not too strong interactions, and valid to very high energies, must be a gauge theory with some scalar and spinor fields.
