The results of the inclusive and differential cross sections measurements for Higgs boson production in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The analysis uses the data set collected with the CMS detector at the LHC in 2022 and corresponds to an integrated luminosity of 34.7 fb \(^{-1}\) . Events in the diphoton decay channel of the Higgs boson ( \(H \rightarrow \gamma \gamma \) ) are selected, and the inclusive cross section in a fiducial region is measured as \( \sigma _{\text {fid}} = 78 \pm 11\,(\text {stat.})^{+6}_{-5}\,(\text {syst.}) \text { fb} \) , in agreement with the Standard Model prediction of \( 67.8 \pm 3.8 \) fb. Differential cross sections are measured for the Higgs boson transverse momentum ( \( p_T^H \) ), rapidity ( \( y^H \) ), and for the number of jets in the event. The differential cross sections also agree with the Standard Model predictions within the uncertainties.

摘要

The results of the inclusive and differential cross sections measurements for Higgs boson production in proton-proton collisions at a centre-of-mass energy of 13.6 TeV are presented. The analysis uses the data set collected with the CMS detector at the LHC in 2022 and corresponds to an integrated luminosity of 34.7 fb \(^{-1}\) . Events in the diphoton decay channel of the Higgs boson ( \(H \rightarrow \gamma \gamma \) ) are selected, and the inclusive cross section in a fiducial region is measured as \( \sigma _{\text {fid}} = 78 \pm 11\,(\text {stat.})^{+6}_{-5}\,(\text {syst.}) \text { fb} \) , in agreement with the Standard Model prediction of \( 67.8 \pm 3.8 \) fb. Differential cross sections are measured for the Higgs boson transverse momentum ( \( p_T^H \) ), rapidity ( \( y^H \) ), and for the number of jets in the event. The differential cross sections also agree with the Standard Model predictions within the uncertainties.
