A Search for High Mass Diphoton Resonances in the Context of the Randall-Sundrum Model in √s = 7 TeV pp Collisions

A search has been performed for evidence of a narrow resonance in the diphoton invariant mass spectrum. The analysis uses the full ATLAS 2010 data set of proton-proton collisions at a center-of-mass energy of √s = 7 TeV, which corresponds to an integrated luminosity of 36 pb−1 . No evidence of a nar...

description A search has been performed for evidence of a narrow resonance in the diphoton invariant mass spectrum. The analysis uses the full ATLAS 2010 data set of proton-proton collisions at a center-of-mass energy of √s = 7 TeV, which corresponds to an integrated luminosity of 36 pb−1 . No evidence of a narrow resonance above the Standard Model background is observed. The results are used to set limits on the production of Randall-Sundrum gravitons decaying into diphoton final states. The results exclude at 95% CL Randall-Sundrum graviton masses below 520 GeV (972 GeV), for values of the dimension less coupling k/MPl of 0.02 (0.1).
