Abstract
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 sqrt[s]=8 TeV and recorded by the ATLAS detector. Cross sections are obtained from measured H→γγ and H→ZZ^{*}→4ℓ 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 σ_{pp→H}=33.0±5.3 (stat)±1.6 (syst) pb. The measurements are compared to state-of-the-art predictions.

This Letter presents measurements of the total and differential cross sections of inclusive Higgs boson production using 20.3 fb−1 of pp collisions produced by the Large Hadrponffiffi Collider (LHC) [1] at a center-of-mass energy of s 1⁄4 8 TeV and recorded by the ATLAS detector [2]
Jets produced in vector-boson fusion (VBF), VH, and ttH processes tend to have higher transverse momenta than those produced via ggF production; the sensitivity to measuring these contributions is weak with the current amount of data
