The Compact Muon Solenoid (CMS) collaboration has developed a complete program of searches beyond the Standard Model (SM) covering a wide range of final states. This document focuses on searches in final states with photons and missing transverse energy ETmiss organised in three analyses. The first two include comparison of the ETmiss distribution (isolation sideband method) in events with either at least two photons plus at least one hadronic jet, or at least one photon plus at least two hadronic jets. The third analysis corresponds to a new approach, the Jet-Gamma Balance (JGB) method, for events with at least one photon plus at least three hadronic jets.We observe no significant deviations from the SM expectation and thus derive upper limits on the signal cross section at the 95% confidence level (CL) for a range of squark, gluino and neutralino mass points in the Gauge Mediated Supersymmetry Breaking scenario.
