John Womersley's Diphoton + Missing ET Analysis

• PRL article as submitted 12/12/96 FERMILAB-Pub-96/446-E, hep-ex-9612011
• Missing ET distribution (Fig.1)
• Cross Section Limits (Fig.2)
• Backup physics note (D0 note 3007)
• The CDF ee gamma gamma MET event (GIF file)
• Transparencies from talk at Collaboration Meeting, November 1996:
  • Introduction
  • Event Selection
  • Typical kinematic distributions for sneutrino pairs and neutralino pairs.
  • Missing ET distribution (same as Fig.1 above)
  • Table of numbers of events
  • D0 and CDF Missing ET distributions overlaid. D0 (this analysis) is yellow histogram, CDF (from diphoton + MET analysis shown by D. Toback at DPF 96) is data points; be careful in interpretation as the cuts are different, but the combination of our detector and selections gives an order of magnitude less background at MET ~ 25 GeV).
  • Cross Section Limits (same as Fig.2 above)
  • Our limits compared with Kane et al. prediction (light neutralino)
  • General Limit
  • Our limits compared with Kane et al. prediction (light gravitino)
  • Our limits compared with Baer et al. prediction
  • Cunclusions
