Search for anomalous production of diphoton events with missing transverse energy at CDF and limits on gauge-mediated supersymmetry-breaking models
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[superscript -1] of pp̅ collisions at √s=1.96 TeV we observe no candidate events, with an expected standard model background of 0.27...

| description | 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[superscript -1] of pp̅ 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[superscript 2], and lightest neutralino of mass less than 93 GeV/c[superscript 2] at 95% C.L. in a gauge-mediated supersymmetry-breaking model with a light gravitino. |
