Description
We discuss the low-energy effective action of a light
goldstino coupled to SM fields by using a manifestly
supersymmetric formalism, in which the goldstino and the
matter fields are represented as constrained superfields. We
discuss the UV sensitivity of the constraints and work out
non-universal goldstino couplings to matter. The latter are
important when the heavy superpartner masses are of the
order of the supersymmetry breaking scale.
