Abstract	These slides presents the results of the searches for new resonances decaying to two photons, based on LHC $pp$ collision data corresponding to an integrated luminosity of 3.2 fb$^{-1}$ at $\sqrt{s}$ = 13 TeV recorded in 2015 with the ATLAS detector. Two different searches are performed, one optimized for a scalar particle, and one targeted for a spin-2 particle, using Randall-Sundrum graviton states as a benchmark model.
