ABSTRACT
There are actually several situations involving one, or more in the case of the supersymmetric version, Higgs boson. These can be presented in a variety of ways and in different gauges. This chapter presents one of these to make the basic idea as simple as possible. It is the first one studied by Peter Higgs himself. Massless scalars or pseudoscalars appear as Goldstone bosons corresponding to the broken generators. Then the mass-less gauge vector or pseudovector bosons absorb the Goldstone bosons and the result is that they develop masses. So Higgs started by making the Goldstone model locally invariant in the, by now, familiar way.
