We consider a low-energy supersymmetric scenario in which the effects
of heavy supersymmetric interactions are included in a model-independe
nt manner through a series of supersymmetric SU(3)(C) x SU(2)(L) x U(1
)(Y) invariant operators; we explicitly construct all such operators o
f dimension less than or equal to 6. From this set, those operators ge
nerated at tree level by the underlying theory are isolated since unde
r weak coupling conditions they are expected to provide the largest ef
fects in low-energy processes. Potential deviations from low-energy pr
edictions in process such as proton decay, neutrinoless double-beta de
cay, and flavor-changing neutral currents are analyzed as illustration
s of the method.
