Title: A Search for Supersymmetry in Events with Photons and Jets from Proton-Proton Collisions at √s = 7TeV with the CMS Detector
Authors: Nandi, Robin James
Item Type: Thesis or dissertation
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.
