Abstract:

We present a detailed description of a search for anomalous production of missing ET (Slashed E signT), jets, leptons (e, 渭, 蟿), b quarks, or additional photons in events containing two isolated, central (|畏|<1.0) photons with ET>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-ET electromagnetic cluster, and large Slashed E signT. We set limits using two specific SUSY scenarios for production of diphoton events with Slashed E signT. 漏1999 The American Physical Society.
