Abstract

We have searched for anomalous production of missing E-T ((E) over bar(T)), jets, leptons (e, mu, tau), b quarks, or additional photons in events containing two isolated, central (\eta\ < 1.0) photons with E-T > 12 GeV. 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-E-T electromagnetic cluster, and large (E) over bar(T). We set limits using two specific supersymmetry scenarios for production of diphoton events with (E) over bar(T).
