A new mechanism for SUSY breaking is proposed. It is not spontaneous breaking of SUSY, and so no hidden sector is needed, and no monstrous cosmological constant problem arises. The mechanism gives rise to SUSY breaking in the SSM proportional to the VEV that breaks gauge symmetry down to SU(3) X U(1). The scheme is very constrained, and it predicts spin one, vector boson, leptons, for example. The mechanism arises from a study of the composite operators in theories like the SSM, using techniques of BRST cohomology and spectral sequences, which show that there are remarkable new phenomena in these theories. These phenomena are hidden from the usual analysis by algebraic subtleties, relating to the equations of motion of the fields.
