Abstract
We study the role of Dterms in supersymmetry SUSY breaking By carefully analyzing the SUSY multiplets containing various conserved currents in theories with global symmetries we obtain a number of constraints on the renormalization group flow in supersymmetric field theories Under broad assumptions these results imply that there are no SUSYbreaking vacua not even metastable ones with parametrically large Dterms This explains the absence of such Dterms in models of dynamical SUSYbreaking There is however a rich class of calculable models which generate comparable Dterms and F terms through a variety of nonperturbative effects these Dterms can be nonabelian We give several explicit examples of such models one of which is a new calculable limit of the 32 model
