Low-scale gauge mediation after LHC Run 2

Low-scale gauge mediation after LHC Run 2

We study low-scale gauge mediated supersymmetry breaking models with a very light gravitino of mass O(1) eV. The cosmological upper bound on the gravitino mass and the collider constraints on the sparticle masses give a significant impact on such models. We consider the weakly coupled gauge mediatio...
