Studies for H → γγ cross-section measurements with 13.6 TeV CMS data — Caio Daumann, Johannes Erdmann, Florian Mausolf, Jan Lukas Späh, and •Maximilian Wrabetz — III. Physikalisches Institut A, RWTH Aachen University

Precise measurements of Higgs boson production cross-sections are crucial for testing the Standard Model. In this presentation, studies for cross-section measurements of Higgs boson production in the diphoton decay channel, based on proton-proton collision data collected at √s =13.6 TeV by the CMS experiment in 2022 and 2023, are shown. They are performed in a fiducial phase space to reduce extrapolation uncertainties and enhance model independence.
The latest studies for a cross-section measurement of LHC Run 3 data are presented. These include the optimization of the categories for the analysis that are based on the estimated diphoton mass resolution and the decorrelation of that estimate with respect to the invariant diphoton mass.
