About this episode
We conclude our series on the standard model with an introduction to gauge theory. We discuss how the requirement of local gauge invariance generates interaction terms in the Lagrangian, and introduce the U(1) x SU(2) x SU(3) group structure of the standard model. We also consider the problem of massive W and Z bosons, and how this was resolved by the introduction of the Higgs field and the mechanism of spontaneous symmetry breaking. Recommended pre-listening is Episode 163: The Standard Model of Particle Physics.
