Abstract
A search for diphoton events with large missing transverse energy is presented. The data were collected pffiffi with the ATLAS detector in proton-proton collisions at s 1⁄4 7 TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3:1 pb␣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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
