Measurement of the total and differential Higgs boson production cross-sections at √s = 13 TeV with the ATLAS detector by combining the H → ZZ∗ → 4` and H → γγ decay channels ATLAS Collaboration
Abstract
The total and differential Higgs boson production cross-sections are measured through a combined statistical analysis of the H → ZZ∗ → 4` and H → γγ decay channels. The results are based on a dataset of 139 fb−1 of proton–proton collisions at a centre-ofmass energy of 13 TeV, recorded by the ATLAS detector at the Large Hadron Collider. 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 ± 2.5 pb. All results from the two decay channels are compatible with each other, and their combination agrees with the Standard Model predictions. A combined statistical interpretation of the measured fiducial cross-sections as a function of the Higgs boson transverse momentum is performed in order to probe the Yukawa couplings to the bottom and charm quarks. A similar interpretation is performed by including also the constraints from the measurements of Higgs boson production in association with a W or Z boson in the H → b ¯b and cc¯ decay channels.

Description |
The total and differential Higgs boson production cross-sections are measured
through a combined statistical analysis of the H → ZZ∗ → 4` and H → γγ decay channels.
The results are based on a dataset of 139 fb−1
of proton–proton collisions at a centre-ofmass energy of 13 TeV, recorded by the ATLAS detector at the Large Hadron Collider.
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 ± 2.5 pb. All results from the two decay channels
are compatible with each other, and their combination agrees with the Standard Model
predictions. A combined statistical interpretation of the measured fiducial cross-sections
as a function of the Higgs boson transverse momentum is performed in order to probe the
Yukawa couplings to the bottom and charm quarks. A similar interpretation is performed
by including also the constraints from the measurements of Higgs boson production in
association with a W or Z boson in the H → b
¯b and cc¯ decay channels.
