Abstract (data abstract)
CERN-LHC. A search for SUSY in the context of GGM breaking with the lightest neutralino as the next-to-lightest SUSY particle and the gravitino as the lightest. The search, with a data sample corresponding to an integrated luminosity of 36 pb-1, uses events containing two or more isolated photons, at least one hadronic jet and significant missing ET. No excess of events at high missing ET is observed and upper limits on the signal cross section for GGM SUSY between 0.3 and 1.1 pb (95% CL) are determined, as tablulated here, for a range of squark, gluino and neutraliino masses.
