Experimental search for chargino and neutralino production via gauge mediated supersymmetry breaking models

=1.8 TeV. 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% CL exclusion region in the supersymmetry parameter space and lower mass bounds of 150 GeV/c

^2

for the lightest chargino and 75 GeV/c

^2

for the lightest neutralino.
