A search for new physics in events with two photons and missing transverse energy is performed. Data corresponding to an integrated luminosity of 4.93 fb−1 in proton-proton collisions at √s = 7 TeV collected by the CMS detector at the Large Hadron Collider are analyzed. No excess of events with large missing transverse energy is observed by comparing the data to the expected standard model processes. The results are interpreted within the general gauge-mediated supersymmetry model and through simplified model spectra. Upper limits on the signal production cross sections and exclusion regions at the 95% confidence level are set in the parameter space of the respective models.
