Abstract
We have calculated the one-loop supersymmetric corrections to
the 
parton scattering subprocesses 
and 
, including form-factor
corrections and box diagrams with internal squarks and gluinos of
arbitrary mass. In general, these exhibit cusps at the corresponding
direct-channel sparticle thresholds. We use these calculations to
make numerical estimates of the possible threshold effects at the
Fermilab Tevatron collider and at the LHC, which depend on the
rapidity range selected, but can be as large as a few percent.
These effects are diluted in the integrated large-ET
cross section, where they are negative.
