Measurements of the Higgs boson production cross section in the four-lepton final state in proton-proton collisions at V¯s = 13.6 TeV

The measurements of the Higgs boson (H) production cross sections performed by the CMS Collaboration in the four-lepton (4l, l = e, µ) final state at a center-of-mass energy V¯s = 13.6 TeV are presented. These measurements are based on data collected with the CMS detector at the CERN LHC in 2022, co...

Descripción
Sumario:The measurements of the Higgs boson (H) production cross sections performed by the CMS Collaboration in the four-lepton (4l, l = e, µ) final state at a center-of-mass energy V¯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 fiducial region closely matching the experimental acceptance, both inclusively and differentially, as a function of the transverse momentum and the absolute value of the rapidity of the four-lepton system. The H --> ZZ --> 4l inclusive fiducial 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
