Tame D-tadpoles in gauge mediation
Riccardo Argurio, Diego Redigolo
We revisit models of gauge mediated supersymmetry breaking where messenger parity is violated. Such a symmetry is usually invoked in order to set to zero potentially dangerous hype…
Collider signatures of goldstini in gauge mediation
Riccardo Argurio, Karen De Causmaecker, Gabriele Ferretti +3
We investigate the collider signatures of the multiple goldstini scenario in the framework of gauge mediation. This class of models is characterized by a visible sector (e.g. the M…
Unscreening the Gaugino Mass with Chiral Messengers
Riccardo Argurio, Matteo Bertolini, Gabriele Ferretti +1
Gaugino screening, the absence of next-to-leading order corrections to gaugino masses, is a generic feature of gauge mediation models of supersymmetry breaking. We show that in a s…
Patterns of Soft Masses from General Semi-Direct Gauge Mediation
Riccardo Argurio, Matteo Bertolini, Gabriele Ferretti +1
We give a general formulation of semi-direct gauge mediation of supersymmetry breaking where the messengers interact with the hidden sector only through a weakly gauged group. Usin…
