Higgs boson production via gluon-gluon fusion and vector-boson fusion in proton-proton collisions is measured in the H→WW∗→eνμνH→WW∗→eνμν 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−1−1. The total cross sections for Higgs boson production by gluon-gluon fusion and vector-boson fusion times the H→WW∗H→WW∗ branching ratio are measured to be 12.0±1.412.0±1.4 and 0.75  −0.16+0.190.75−0.16+0.19​ pb, respectively, in agreement with the Standard Model predictions of 10.4±0.610.4±0.6 and 0.81±0.020.81±0.02 pb. Higgs boson production is further characterized through measurements of Simplified Template Cross Sections in a total of 11 kinematic fiducial regions.
