Abstract

The measurements of the Higgs boson (H) production cross sections performed by the CMS Collaboration in the four-lepton (4ℓ, ℓ = e, µ) fnal state at a center-of-mass energy √s = 13.6 TeV are presented. These measurements are based on data collected with the CMS detector at the CERN LHC in 2022, corresponding to an integrated luminosity of 34.7 fb−1. Cross sections are measured in a fducial region closely matching the experimental acceptance, both inclusively and diferentially, as a function of the transverse momentum and the absolute value of the rapidity of the four-lepton system. The H → ZZ → 4ℓ inclusive fducial cross section is measured to be 2.89+0.53−0.49(stat)+0.29−0.21(syst)fb, in agreement with the standard model expectation of 3.09+0.27−0.24 fb.
