A common source for neutrino and sparticle masses / Brignole, Andrea (INFN, Padua) ; Joaquim, Filipe R. (CERN) ; Rossi, Anna (Padua U.)
We discuss supersymmetric scenarios in which neutrino masses arise from effective d=6 operators in the Kahler potential (including SUSY-breaking insertions). Simple explicit realizations of those Kahler operators are presented in the context of the type II seesaw. [...]

Beyond the standard seesaw : neutrino masses from Kahler operators and broken supersymmetry / Brignole, Andrea (INFN, Padua) ; Joaquim, Filipe R. (CERN) ; Rossi, Anna (Padua U.)
We investigate supersymmetric scenarios in which neutrino masses are generated by effective d=6 operators in the Kahler potential, rather than by the standard d=5 superpotential operator. First, we discuss some general features of such effective operators, also including SUSY-breaking insertions, and compute the relevant renormalization group equations. [...]

Four-fermion interactions and sgoldstino masses in models with a superlight gravitino / Brignole, Andrea (INFN, Padua ; Padua U. ; Lisbon, IST) ; Feruglio, Ferruccio (INFN, Padua ; Padua U. ; CERN) ; Zwirner, Fabio (INFN, Padua ; Padua U.)
We discuss the role of the effective interactions among four matter fermions in supersymmetric models with a very light gravitino. We show that, from a field-theoretical viewpoint, no model-independent bound on the gravitino mass can be derived from such interactions. [...]

Signals of a superlight gravitino at hadron colliders when the other superparticles are heavy / Brignole, Andrea (INFN, Padua ; Padua U.) ; Feruglio, Ferruccio (INFN, Padua ; Padua U. ; CERN) ; Mangano, Michelangelo L. (CERN) ; Zwirner, Fabio (INFN, Padua ; Padua U.)
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 gravitinos and ordinary particles in the final state. We compute here the cross-sections for some distinctive signals at hadron colliders: photon plus missing energy, induced by (q antiquark -> G G photon), and jet plus missing energy, induced by (q antiquark -> G G g), (q g -> G G q), and (g g -> G G g).

Signals of a superlight gravitino at $e^+ e^-$ colliders when the other superparticles are heavy / Brignole, Andrea (CERN) ; Feruglio, Ferruccio (CERN) ; Zwirner, Fabio (INFN, Padua)
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 gravitinos and ordinary particles in the final state. We compute here the cross-section for the process e^+ e^- ==> G G gamma, whose final state can give rise to a distinctive photon plus missing energy signal at present and future e^+ e^- colliders.

On the effective interactions of a light gravitino with matter fermions / Brignole, Andrea (CERN) ; Feruglio, Ferruccio (Padua U.) ; Zwirner, Fabio (INFN, Padua)
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 ordinary matter. To discuss the model-dependence of these interactions, we take the simple case of spontaneously broken supersymmetry and only two chiral superfields, associated with the goldstino and a massless matter fermion.
