  A search for physics beyond the standard model involving events with one or
more photons, jets, and missing transverse energy has been performed by the CMS
experiment. The data sample corresponds to an integrated luminosity of 4.93
inverse femtobarns of proton-proton collisions at sqrt(s) = 7 TeV, produced at
the Large Hadron Collider. No excess of events with large missing transverse
energy is observed beyond expectations from standard model processes, and upper
limits on the signal production cross sections for new physics processes are
set at the 95% confidence level. The results of this search are interpreted in
the context of three models of new physics: a general model of gauge-mediated
supersymmetry breaking, Simplified Models, and a theory involving universal
extra dimensions. In the absence of evidence for new physics, exclusion regions
are derived in the parameter spaces of the respective models.
