Résumé
Higgs boson production via gluon-gluon fusion and vector-boson fusion in proton-proton collisions is measured in the H → W W ∗ → e ν μ ν decay channel. The Large Hadron Collider delivered proton-proton collisions at a center-of-mass energy of 13 TeV between 2015 and 2018, which were recorded by the ATLAS detector, corresponding to an integrated luminosity of 139     fb − 1 . The total cross sections for Higgs boson production by gluon-gluon fusion and vector-boson fusion times the H → W W ∗ branching ratio are measured to be 12.0 ± 1.4 and 0.75   + 0.19 − 0.16     pb , respectively, in agreement with the Standard Model predictions of 10.4 ± 0.6 and 0.81 ± 0.02     pb . Higgs boson production is further characterized through measurements of Simplified Template Cross Sections in a total of 11 kinematic fiducial regions.
