  These notes are intended to provide an introduction to supersymmetry. The
notes begin with supersymmetric quantum mechanics and the basic properties of
spinor fields. The supersymmetry of simple theories of spin-zero and
spin-one-half fields is discussed with emphasis upon the charges that generate
the transformations of supersymmetry. Abelian and non-abelian supersymmetric
gauge theories are characterized in their simpler and more general forms.
Superfields are defined, and the concise notation they make possible is
described. The minimal supersymmetric standard model is discussed with
particular attention to the Higgs fields and the electro-weak superpotential.
