Abstract : The data collected from 2016 to 2018 during Run 2 of the LHC has enabled measurements of the Higgs boson's properties to reach unprecedented precision. In this seminar, I will present a recent analysis from the CMS Collaboration in which production properties of the Higgs boson are measured using the diphoton decay channel. All major Higgs boson production mechanisms are considered, enabling a wide range of cross section and coupling measurements to be performed. Highlights include the first CMS measurement of Higgs boson production in association with a single top quark in this decay channel, and a simultaneous measurement of 27 independent Higgs boson production parameters. So far, all results are found to be compatible with the corresponding Standard Model predictions.
