Description

The measurements of differential (in the fiducial phase space) and production mode cross sections are presented in the $H\rightarrow\gamma\gamma$ decay channel using $36~\text{fb}^{-1}$ data collected by the ATLAS detector at a centre of mass energy of $\sqrt{s}=13~\text{TeV}$. These characterise $pp\rightarrow H\rightarrow\gamma\gamma$ processes in a variety of ways; production mode cross sections directly test the compatibility of the data with the Standard Model (SM), whereas fiducial measurements make minimal SM assumptions and can thus be re-interpreted in order to constrain new physics models. The sensitivity is approximately double that of the $\sqrt{s}=8~\text{TeV}$ dataset. Finally, 5 differential distributions are used to constrain several Wilson coefficients using the effective field theory approach.
