We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at root s = 1.8 TeV.

Inferred limits on squark and gluino masses depend on the supersymmetry model parameters. The particular choices mu = -40 GeV/c(2) and tan beta = 1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/c(2) and 140 GeV/c(2) for squarks and gluinos, respectively.

Abstract

We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at root s = 1.8 TeV. Events containing two photons plus large missing transverse energy were investigated. The observed event rate and the missing transverse energy distribution of the two-photon events are consistent with QCD predictions. Inferred limits on squark and gluino masses depend on the supersymmetry model parameters. The particular choices mu = -40 GeV/c(2) and tan beta = 1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/c(2) and 140 GeV/c(2) for squarks and gluinos, respectively.
