The Higgs Mechanism
This lecture delves into the formal aspects of the Higgs mechanism, explaining the origin of the Higgs bosons' properties. It covers the appearance of mass terms for scalar and gauge fields, the full Higgs mechanism by breaking local gauge symmetry, and the symmetry breaking for a complex scalar field. The lecture also explores interacting scalar fields, the vacuum state, and the interactions of scalar particles. It concludes with an overview of the standard model Higgs boson, discussing the extension to local gauge symmetry, the masses of gauge bosons, and the interactions of the Higgs boson with gauge bosons.
