THE SUPERCURRENT IN SUPERSYMMETRIC FIELD THEORIES

Abstract

A supercurrent superfield whose components include a conserved energy-momentum tensor and supersymmetry current as well as an (generally broken) R symmetry current is constructed for a generic effective N=1 supersymmetric gauge theory. The general form of the R symmetry breaking is isolated. Included within the various special cases considered is the identification of those models which exhibit an unbroken R symmetry. One such example corresponds to a nonlinearly realized gauge symmetry where the chiral field R weight is required to vanish.
