Search for supersymmetry with gauge-mediated breaking in diphoton events with missing transverse energy at CDF II

Abstract: We present the results of a search for supersymmetry with gauge-mediated breaking and ??01???G in the ??+missing transverse energy final state. In 2.6±0.2??fb?1 of p¯p 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 world?s best limit of 149??GeV/c2 on the ??01 mass at ???01?1??ns. We also exclude regions in the ??01 mass-lifetime plane for ???01?2??ns.
