    We present the results of a search for anomalous production of diphoton events with large missing transverse energy using the Collider Detector at Fermilab. In 202 pb -1 of pp̄ collisions at √s = 1.96 TeV we observe no candidate events, with an expected standard model background of 0.27 ± 0.07(stat) ± 0.10(syst) events. The results exclude a lightest chargino of mass less than 167 GeV/c 2, and lightest neutralino of mass less than 93 GeV/c 2 at 95% C.L. in a gauge-mediated supersymmetry-breaking model with a light gravitino. © 2005 The American Physical Society.
