Global Symmetries and D-Terms in Supersymmetric Field Theories

Understand

We study the role of D-terms 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 SUSY-breaking vacua, not even metastable ones, with parametrically large D-terms.
• This explains the absence of such D-terms in models of dynamical SUSY-breaking.
