Abstract

We present a detailed description of a search for anomalous production of missing

E_{T}

({E /}_{T}),

jets, leptons

(e, μ, τ),

b quarks, or additional photons in events containing two isolated, central

(| η | < 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 /}_{T} .

We set limits using two specific SUSY scenarios for production of diphoton events with

{E /}_{T} .
