Query: Soft supersymmetry breaking and finiteness   We calculate the two-loop $\beta$-functions for soft supersymmetry-breaking
interactions in a general supersymmetric gauge theory, emphasising the role of
the evanescent couplings and masses that are generic to a non-supersymmetric
theory. We also show that a simple set of conditions sufficient for one-loop
finiteness renders a theory two-loop finite, and we speculate on the possible
significance of finite softly broken theories.
