Signals of a superlight gravitino at $e^+ e^-$ colliders when the other superparticles are heavy
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...
