Physical Review Letters Vol. 115, № 9. P. 091801-1-091801-19Abstract: Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3 fb-1 of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of yjs = 8 TeV and recorded by the ATLAS detector. Cross sections are obtained from measured H ^ yy and H ^ ZZ* ^ 41 event yields, which are combined accounting for detector efficiencies, fiducial acceptances, and branching fractions. Differential cross sections are reported as a function of Higgs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transverse momentum of the leading jet. The total production cross section is determined to be ffpp^H = 33.0 ± 5.3 (stat) ± 1.6 (syst) pb. The measurements are compared to state-of-the-art predictions.
