  Over the last few years lattice techniques have been used to investigate
candidate theories of new physics beyond the Standard Model. This review gives
a survey of results from these studies. Most of these investigations have been
of systems of gauge fields and fermions that have slowly-running coupling
constants. A major portion of the review is a critical discussion of work in
this particular subfield, first describing the methods used, and then giving a
compilation of results for specific models.
