Search for Squarks and Gluinos via Radiative Decays of Neutralinos in Proton-Antiproton Collisions at √s=1.8 TeV Academic Article uri icon

abstract

  • We have sought evidence for radiative decays of neutralinos produced in proton-antiproton collisions at 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 =-40 GeV/c2 and tan=1.5 lead to 90%-confidence-level asymptotic lower limits of 110 GeV/ c2 and 140 GeV/ c2 for squarks and gluinos, respectively. © 1995 The American Physical Society.
