Query: Low-Energy Supersymmetry: Prospects and Challenges   An introduction to the minimal supersymmetric Standard Model (MSSM) is given.
The motivation for ``low-energy'' supersymmetry is reviewed, and the structure
of the MSSM is outlined. In its most general form, the MSSM can be viewed as a
low-energy effective theory parametrized by a set of arbitrary
soft-supersymmetry-breaking parameters. A variety of techniques for reducing
the parameter freedom of the MSSM are surveyed. The search for supersymmetry
below and above the threshold for supersymmetric particle production presents a
challenging task for experimentalists at present and future colliders.
