Abstract
We present the results of a search for supersymmetry with gauge-mediated breaking and χ10→γG in the γγ+missing transverse energy final state. In 2.6±0.2  fb-1 of pp̅ collisions at √s=1.96  TeV recorded by the CDF II detector we observe no candidate events, consistent with a standard model background expectation of 1.4±0.4 events. We set limits on the cross section at the 95% C.L. and place the worlds best limit of 149  GeV/c2 on the χ10 mass at τχ10≪1  ns. We also exclude regions in the χ10 mass-lifetime plane for τχ10≲2  ns.
