Sumario:We present measurements of the total and differential cross sections of Higgs boson production that were 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 $H \to \gamma\gamma$ and $H \to ZZ \to 4 \ell$ 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: $\sigma_{pp \to H} = 33.0 \pm 5.3 \, (\text{stat}) \pm 1.6 \, (\text{sys})$ pb. The measurements are then compared to state-of-the-art predictions.
