Abstract

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65-600 {GeV} is performed using 20.3 fb(-1) of root s = 8 {TeV} pp collision data collected with the {ATLAS} detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95\% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches.
