Measurement of the total and differential Higgs boson production cross-sections at √s = 13 TeV with the ATLAS detector by combining the H→ZZ^∗→4ℓ and H→γγ decay channels

The total and differential Higgs boson production cross-sections are measured through a joint analysis of the H→ZZ^∗→4ℓ and H→γγ decays. The results are based on a dataset of 139 fb⁻¹ of proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. The measured total Higgs boson production cross-section is 55.5^+4.0_−3.8 pb, consistent with the Standard Model prediction of 55.6±2.8 pb. All results from the two decay channels are compatible with each other, and their combination agrees with the Standard Model predictions. A joint interpretation of the measured Higgs boson fiducial transverse momentum distributions is performed and combined with measurement results from H→bb̅/cc̅ to probe the Yukawa couplings to the bottom and charm quarks.
