Measurement of production cross sections and coupling properties of the Higgs boson in decays to two photons using the ATLAS detector

This report summarizes the results of the measurement of production cross sections and coupling properties of the Higgs boson in decays to two photons. The measurement is performed using $79.8\ \rm{fb}^{-1}$ of data from LHC proton-proton collisions at the center-of-mass energy of $\sqrt{s}$ $= 13$ TeV recorded by the ATLAS experiment. These results have improved precision compared to the results previously reported by ATLAS which used $36\ \rm{fb}^{-1}$ of data. Differential cross section measurements targeting gluon-gluon fusion production in association with $b$-jets have also been added.
