Measurements of the fiducial cross section performed in the H→γγ decay channel are presented for Higgs boson production in proton-proton collisions at center-of-mass energies of 7, 8 and 13 TeV at the ATLAS experiment. Values for the measured total production cross section for a Standard Model Higgs boson are also given. The signal is extracted using a fit to the diphoton invariant-mass spectrum assuming that the natural width of the resonance is much smaller than the experimental resolution. The signal yield is corrected for the effects of detector efficiency and resolution. The measured cross sections, statistically limited, are in agreement with Standard Model expectation.
