Search for Anomalous Diphoton+X Production

Search for Anomalous Diphoton+X Production

This document describes a search for events with two photons and additional identified objects. So far, the additional object may be an electron, muon, or a third photon. The data are collected in p-pbar collisions at qrt(s)=1.96 TeV with the CDF detector at the Fermilab Tevatron, Run II. We use nominal high-Et object identification and kinematic selections. We report observed event counts, Standard Model background predictions, and kinematic distributions.
