Abstract
An exclusion of Gauge Mediated Supersymmetry Breaking at 95% confidence level is
made in the squark mass vs gluino mass parameter space using 1:1 fb -1 of proton-proton
collisions data from the Large Hadron Collider. The event selection is based on the strong
production signature of photons, jets and missing transverse energy. Missing transverse
energy is used to distinguish signal from background. The background is estimated with
a data driven technique. The CLs method is used to exclude models with squark mass
and gluino mass up to around 1TeV.
