Electroweak Theory involves two parts: weak interaction and electromagnetic interaction. In chapter 1, introducing the prototype quantum-field theory: QED, and some simple weak interaction processes, and the mesons W and Z0 appear.
Chapter 2 discussing the spontaneously syrnnetry breakint. There are three examples in this chapter: simplest example, Goldstone Boson and Higgs Mechanics. By these examples, we can know how symmetry is broken and what will appear. Finally, introducing the stand model of electroweak theory. By choosing apporpriate gauge groups, SU(2) and U(1), we can see how the weak and electromagnetic interactions are unified, and understand the masses about W and Z0 particles.
