EFFECTIVE OPERATORS IN SUPERSYMMETRY

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.
