  A fairly elementary introduction to supersymmetric field theories in general
and the minimal supersymmetric Standard Model (MSSM) in particular is given.
Topics covered include the cancellation of quadratic divergencies, the
construction of the supersymmetric Lagrangian using superfields, the field
content of the MSSM, electroweak symmetry breaking in the MSSM, mixing between
different superparticles (current eigenstates) to produce mass eigenstates, and
the embedding of the MSSM in so--called minimal supergravity.
