Measurements of the Higgs boson production cross section in the four-lepton final state in proton-proton collisions at $$\sqrt{s}$$ = 13.6 TeV

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.
