Searches for New Physics in Diphoton Events in proton anti-proton collisions at sqrt(s)=1.8TeV

Abstract

We present a detailed description of a search for anomalous production of missing E_T ($\text{mett}$), jets, leptons ($e,\mu ,\tau$), b-quarks, or additional photons in events containing two isolated, central ($|\eta |<1.0$) photons with $\text{Et}>12$ 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-E_T electromagnetic cluster, and large $\text{mett}$. We set limits using two specific SUSY scenarios for production of diphoton events with $\text{mett}$.
