Theory of Electroweak Gauge Interactions

Abstract

The conditions obtained by Salam for a general gauge theory to be renormalizable are derived. They require that in a gauge invariant formalism the bare boson mass associated with the massive non-Abelian vector field is zero. A solution to the origin of masses in electroweak theory is proposed in which the physical masses of the $W$ and $Z$ bosons and the quarks and leptons are derived from their self-energies according to a self-consistent scheme.
