Searching for Supersymmetry with Final State Photons at ATLAS

Gauge-mediated Supersymmetry-breaking has a propensity to provide scenarios for which the next-to-lightest Supersymetric particle is a neutralino that decays promptly to an essentially massless gravitino. In many of these scenarios the NLSP neutralino has significant bino (SUSY partner of the U(1) gauge boson) content, which in turn possesses significant coupling to the photon. Thus, a major thrust in the possible discovery of gauge-mediated SUSY is the search for events with significant missing energy accompanied by one or more photons. I'll discuss the searches that are being done on ATLAS, their results to date, and some thoughts about where ATLAS might be headed in the future with regard to photon + missing energy final states.
