Signals of a superlight gravitino at e^+ e^- colliders when the other superparticles are heavy
Andrea Brignole, Ferruccio Feruglio, Fabio Zwirner
If the gravitino G is very light and all the other supersymmetric particles are above threshold, supersymmetry may still be found at colliders, by looking at processes with only gr…
On the effective interactions of a light gravitino with matter fermions
Andrea Brignole, Ferruccio Feruglio, Fabio Zwirner
If the gravitino is light and all the other supersymmetric particles are heavy, we can consider the effective theory describing the interactions of its goldstino components with or…
Soft supersymmetry-breaking terms from supergravity and superstring models
A. Brignole, L. E. Ibañez, C. Muñoz
We review the origin of soft supersymmetry-breaking terms in N=1 supergravity models of particle physics. We first consider general formulae for those terms in general models with…
Aspects of spontaneously broken N = 1 global supersymmetry in the presence of gauge interactions
Andrea Brignole, Ferruccio Feruglio, Fabio Zwirner
We discuss models where N=1 global supersymmetry is spontaneously broken, at the classical level, in the presence of non-anomalous gauge interactions. We take such models as effect…
