Decoupling and Destabilizing in Spontaneously Broken Supersymmetry

Understand

The supersymmetric analog of the Goldberger-Treiman relation plays a critical role in the low energy effective theory of models in which supersymmetry is spontaneously broken in a hidden sector.

• The interactions that connect the hidden and visible sectors break a global symmetry, which implies that the low energy theory must be constructed consistently in inverse powers of the messenger scale.
• The Goldberger-Treiman relation determines the couplings of the Goldstino to the visible sector fields.
• These couplings are fixed by the soft supersymmetry breaking terms within a power counting scheme that is stable under radiative corrections.
