Description
Low energy (multi-TeV) supersymmetry breaking is an interesting possibility since it alleviates the little hierarchy problem in a natural and minimal way. This scenario generally predicts an almost massless gravitino whose dynamics are effectively described by its goldstino component. Focusing on the Minimal Supersymmetric Standard Model, the corresponding effective theory would be that of MSSM plus goldstino. We construct the most general effective Lagrangian by using the constrained superfields formalism and comment on its phenomenological consequences.
