Higgs differential cross section and STXS measurements at CMS

TL;DR

This paper reports on detailed measurements of Higgs boson production rates and cross sections in various decay channels using CMS data, including new results from early Run 3, to test the Standard Model and probe potential new physics.

Contribution

It provides the first set of differential Higgs cross section measurements with early Run 3 data and applies these to constrain Higgs couplings within the Standard Model Effective Field Theory framework.

Findings

Differential cross sections measured in bosonic and fermionic channels

Limits on Higgs couplings derived from fiducial measurements

First differential measurements with early Run 3 data

Abstract

In this manuscript, we present the latest differential measurements of Higgs boson cross sections with the CMS detector in bosonic and fermionic decay channels. Both fiducial differential cross section measurements and measurements in the simplified template cross section framework are presented. The fiducial measurements are then used to compute limits on Higgs couplings using the Standard Model Effective Field Theory. The results are based on data collected during Run 2 of the LHC by the CMS experiment. First set of differential measurements with early Run 3 data are also reported.
