Abstract
We search for inclusive high diphoton events with large missing transverse energy in collisions at . Such events are expected from pair production of charginos and neutralinos within the framework of the minimal supersymmetric standard model with a light gravitino. No excess of events is observed. In that model, and assuming gaugino mass unification at the GUT scale, we obtain a 95% C.L. exclusion region in the supersymmetry parameter space and lower mass bounds of for the lightest chargino and for the lightest neutralino.
