Measurements of the total cross sections for Higgs boson production combining the and decay channels at 7, 8 and 13 TeV center-of-mass energies with the ATLAS detector
Measurements of total cross sections are presented for Higgs boson production in proton-proton collisions recorded by the ATLAS detector at the Large Hadron Collider. The data correspond to 4.5 fb collected at the center-of-mass energy of 7 TeV, 20.3 fb at 8 TeV, and most recently 3.2 fb at 13 TeV. Cross sections are obtained from measured and event yields, which are combined accounting for detector effects, fiducial acceptances and branching fractions. The total Higgs boson production cross sections are measured to be pb, pb, and pb for center-of-mass energies of 7, 8 and 13 TeV, respectively. These measurements are compared to state-of-the-art Standard Model theoretical predictions.
