Search for new phenomena in events with at least three photons collected in pp collisions at s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in events with at least three photons are reported. Data from proton–proton collisions at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 20.3 fb-1$$^{-1}$$, were collected with the ATLAS detector at the LHC. The observed data are
