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...

| description | 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 mediation models with (meta)stable SUSY breaking vacua and grand unification. We apply the latest results of the LHC to these models and obtain the current constraints. We find that perturbatively calculable classes of low-scale gauge mediation models can be largely excluded. |
