Search for Diphoton Events with Large Missing Transverse Energy in 7 TeV Proton-Proton Collisions with the ATLAS Detector
A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at √s=7 [square root of s=7] TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1 pb-1 [pb superscript -1]....

| Summary: | A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at √s=7 [square root of s=7] TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1 pb-1 [pb superscript -1]. No excess of such events is observed above the standard model background prediction. In the context of a specific model with one universal extra dimension with compactification radius R and gravity-induced decays, values of 1/R<729 GeV are excluded at 95% C. L., providing the most sensitive limit on this model to date. United States. Dept. of Energy National Science Foundation (U.S.) |
