Measurements of gluon–gluon fusion and vector-boson fusion Higgs boson production cross-sections in the H → WW ^⁎ → eνμν decay channel in pp collisions at √s=13TeV with the ATLAS detector

Higgs boson production cross-sections in proton–proton collisions are measured in the H→WW ^⁎→eνμν decay channel. The proton–proton collision data were produced at the Large Hadron Collider at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1fb ⁻¹. The product of the H→WW ^⁎ branching fraction times the gluon–gluon fusion and vector-boson fusion cross-sections are measured to be 11.4 _−1.1 ^+1.2(stat.) _−1.7 ^+1.8(syst.)pb and 0.50 _−0.22 ^+0.24(stat.)±0.17(syst.)pb, respectively, in agreement with Standard Model predictions.
