We have searched for anomalous production of missing ET(ET), jets, leptons (e, μ, τ), bquarks, or additional photons in events containing two isolated, central (|η| < 1.0) photons with ET > 12GeV. The results are consistent with standard model expectations, with the possible exception of one event that has in addition to the two photons a central electron, a high-ET electromagnetic cluster, and large ET. We set limits using two specific supersymmetry scenarios for production of diphoton events with ET. © 1998 The American Physical Society.
