Search for Supersymmetry in Gauge Mediated SUSY breaking scenarios

Four CMS searches for Gauge Mediated Supersymmetry in up to 20 fb-1 data collected at a center of mass energy of 8 TeV are discussed in this article. Different analysis strategies have been pursued to ensure a good coverage of possible signal scenarios at the best possible sensitivity. Wino-like neutralino mixings are probed in the single-photon final state, while the di-photon final state is most sensitive to bino-like neutralino mixings. Abandoning the large discriminating power of a missing transverse energy requirement opens the sensitivity to a wide range of scenarios but requires novel background estimation techniques developed by the analysis of Stealth Supersymmetry. A fourth analysis uses the multi-lepton final state to search for electroweak produced Supersymmetry. No excess of data over the Standard Model expectation has been observed and upper limits on various signal cross sections were calculated and interpreted in the scenario of General Gauge Mediation.
