Sommaire:

First, I will briefly introduce some aspects of supersymmetry breaking and its mediation to the MSSM. I will then consider a scenario with two decoupled susy breaking hidden sectors, where one expects to find two light fermions in the spectrum: the goldstino and the pseudo-goldstino. I will show that in gauge mediation the pseudo-goldstino acquires a mass through radiative corrections, which is naturally around the GeV scale. I will introduce a simplified model that encodes the pseudo-goldstino mass and couplings, and I will discuss some of the phenomenological consequences and possible collider signatures.
