Abstract
We present the results of a search for supersymmetry with gauge-mediated breaking and χ̃10→γG̃ in the γγ+missing transverse energy final state. In 2.6±0.2fb-1 of pp̄ collisions at s=1.96TeV 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 world's best limit of 149GeV/c2 on the χ̃10 mass at τχ̃10≪1ns. We also exclude regions in the χ̃10 mass-lifetime plane for τχ̃10≪2ns. © 2010 The American Physical Society.
