Abstract: The first measurements of Higgs boson production cross-sections performed by the CMS Collaboration in the four-lepton final state at the increased center-of-mass energy of $ \sqrt{s} = $ 13.6 TeV are presented. This analysis relies on the 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 close to that of the detector acceptance, both inclusively and differentially, as a function of the transverse momentum and the rapidity of the four-lepton system. The $ \text{H}\to\text{ZZ}\to 4\ell $ inclusive fiducial cross section is measured to be 2.94 $ ^{+0.53}_{-0.49} $ (stat.) $ ^{+0.29}_{-0.22} $ (syst.) fb. The results are compared with the SM predictions and all results are found to be consistent with the SM expectations within uncertainties in the considered phase space. | ||

Table 3:
Post-fit yields with their corresponding post-fit uncertainties for the different final states in the signal region (105 $ < m_{4\ell} < $ 160 GeV) and for an integrated luminosity of 34.7 fb$^{-1}$. The nonfid contribution arises from signal events not originating from the fiducial volume but satisfying the analysis selection, while the nonres contribution contains signal events from VH or $ \mathrm{t}\bar{\mathrm{t}}\mathrm{H} $ where one of the leptons from the H boson decay is lost or not selected (more details in Section 6). |

Summary |
This note presents the first measurement of the differential fiducial cross section in the 4 $ \ell $ final state using the first Run 3 data collected with the CMS detector at the increased center-of-mass energy of $ \sqrt{s}= $ 13.6 TeV. The $ \mathrm{H}\to\mathrm{Z}\mathrm{Z}\to4\ell $ inclusive fiducial cross section is measured to be 2.94 $ ^{+0.53}_{-0.49} $ (stat.) $ ^{+0.29}_{-0.22} $ (syst.) fb, in good agreement with the SM expectation of 3.09 $ ^{+0.27}_{-0.24} $ fb. The differential fiducial cross section is also measured in bins of the transverse momentum and absolute value of the rapidity of the H boson. The results are compared with the SM predictions and the theoretical uncertainties are evaluated. All results are found to be consistent with the SM expectations within uncertainties in the considered phase space. |
